I’m launching a web-based store and need a developer who can build the entire e-commerce application from the ground up. The core focus is a smooth online buying experience that supports bank transfers as the mandatory payment option, so the checkout flow, order tracking, and confirmation emails all have to work flawlessly with that method. Beyond payments, I’ll rely on you to craft a modern, responsive front-end, a secure back-end, and the usual product, cart, and inventory modules. Clean code, clear documentation, and an eye for performance and security best practices are essential because I expect to scale traffic quickly after launch. If you’ve built similar web apps, especially those that integrate custom payment gateways or bank-transfer workflows, I’d l...

I’m planning a full-featured cosmetics store built with Flutter for both iOS and Android. The core of the app is straightforward: customers browse an attractive catalogue, add items to their cart, pay securely, and leave ratings or reviews that appear in real time. I want phone-number OTP to be the one and only way users create an account and sign in; email or social logins can stay out of scope for now. For payments, the checkout flow must support credit and debit cards alongside two local options—Vodafone Cash and InstaPay—so please factor in the necessary gateways or custom API work. If you prefer Stripe, Paymob, or another processor, let me know the pros and cons for these specific wallets. High-level deliverables • Flutter source code structured for easy mai...

I am building a cross-platform cab booking solution and need a developer who can deliver the front-end in Flutter while exposing all server interactions through my existing API layer. The finished app must compile cleanly for both iOS and Android from a single codebase and feel fully native on each platform. At this stage I want the essentials in place: new riders must be able to create an account, sign in securely and remain authenticated across sessions. Once logged in they should see the three vehicle categories I operate—Standard cars, Luxury cars and the larger Vans & SUVs—and be able to select whichever fits their trip. Because the API endpoints are already defined in , your focus will be on integrating those calls, handling state, and presenting responsive UI that...

I’m launching a modern online store and need it designed and built end-to-end. The finished site must look clean and professional, load quickly on mobile and desktop, and guide shoppers smoothly from discovery to purchase. Core features I have to see on day one: • Product catalog with robust search and filtering • Seamless shopping cart and secure checkout flow • Section for verified customer reviews and ratings I’m open to your suggestions on the tech stack—whether you lean toward a SaaS platform or a custom framework, explain why it’s the best fit for performance, scalability, and easy maintenance. Show me two or three live stores you’ve produced that prove you can deliver the polish and speed I’m after. When you reply, please i...

We are a bookkeeping and financial consulting firm working with small business owners and entrepreneurs. Our clients are great at running their businesses but are not financially savvy, and our mission is to change that. We are building a Financial Intelligence Portal that sits on top of QuickBooks and turns raw bookkeeping data into simple, meaningful insights that any business owner can understand and act on - without needing to know what a balance sheet or EBITDA means. We already have a working version of the portal live with the frontend, database, and core financial engine in place. We now need an experienced developer to complete it. Full technical details, codebase documentation, database schema, and a clear list of what needs to be built are attached. Please review before apply...

I need a fully-functional crypto trading setup that lets me connect to multiple exchanges, pull live market data, place and manage orders in real time, and track overall performance from a single dashboard. The core of the job is to design and code a clean, secure engine that I can later expand with my own indicators and strategies. Key expectations: • Real-time price feeds with robust error handling • Fast order execution through REST and WebSocket APIs • Risk controls (position sizing, stop-loss, max drawdown guard) • Modular architecture so I can drop in new strategies without rewriting the core • Clear, commented source code plus a short README explaining deployment and configuration Deliver the project as a Git repository. A quick demo video or scree...

For Project 40648634 - AI Commodity Intelligence Platform Workflow you need: Collect → Analyze → Compare → Score → Challenge → Recommend → Risk-check → Present. Research only, no auto-trading. Client approves/rejects. Stack for Phase 1: GitHub + Codespaces (free allowance) + Python + SQLite + Streamlit + OpenAI API + Scheduler + GitHub Secrets. Using Codex as an agentic engineer. What I will build: 1. Ingest: Weather (Open-Meteo/NOAA), Gov Reports (USDA WASDE/FAO PDF scraper + LLM summary), News RSS, Prices (Yahoo/FRED). Modular for satellite/NDVI later. 2. Core: SQLite schema (raw_data, evidence, scores), ETL, scoring 0-100 [30% supply stress, 25% demand, 20% news sentiment, 15% price anomaly, 10% risk], anomaly detection. 3. Challenge/Risk-check: ...

I need a robust yet lightweight solution that continuously gathers two kinds of information—user comments & posts and the hashtags or topic trends that surround them—so I can run reliable sentiment analysis afterwards. The sources in scope are Facebook, Twitter (X), Instagram, YouTube and Snapchat, both recent activity and a defined slice of historical data where accessible. Here is what will make the project a success for me: • A scraper or API-based pipeline (Python preferred, but I am open to Node or R) that respects each platform’s rate limits and terms of service • Clean, deduplicated output in CSV or JSON with at least these fields: platform, date/time, raw text, hashtag list, basic engagement numbers, and an anonymised user ID • Simple conf...

I am building a full-scale education SaaS platform and need a developer who already has solid, demonstrable experience delivering multi-tenant software-as-a-service products. Because many of the strategic decisions will be easier to hash out in person, I can only move forward with professionals based in Kolkata, Howrah, or Hooghly—ideally someone who is comfortable meeting face-to-face to white-board ideas, refine milestones, and review progress. The product will cover typical education workflows (think enrolment, course delivery, assessments, possible analytics dashboards), but the exact feature set will be finalised together. My primary requirement is a clean, scalable architecture that can accommodate future modules without major rewrites. Performance, security, and an intuitive ...

I need a production-ready cab-hailing application built with Flutter so it runs smoothly on both iOS and Android from a single codebase. The mobile client will consume a fresh set of ASP.NET Core Web APIs that you create and host; the APIs should follow REST best practices, be fully documented, and stay modular so extra features can slip in later without rewrites. For this first release the essentials are straightforward: riders must be able to request a ride, see available drivers, and once the trip ends, leave a rating and short review for the driver. No real-time map tracking or payment gateway is required right now, but keep the data models and endpoints flexible so we can introduce those options down the road. Login should be quick and frictionless—users enter their phone numb...

# Build an AI-Powered Personal Training Studio Management App — MVP ## Project Overview We are looking for an experienced **Full-Stack Developer / App Development Team** to build the MVP of **Ulpha Coaching OS**, an AI-powered coaching and studio management platform designed for in-person personal training studios. This is **not simply a workout tracking app**. The goal is to create a centralized operating system connecting **studio owners, personal trainers and clients**, while using AI to improve coaching quality, client accountability, progress tracking and studio operations. We are initially looking to build a scalable MVP, with the potential for continued development and a long-term partnership. ## User Roles The application will initially support three main user types: ...

I earn revenue from reward programs that credit me each time an advertisement is fully viewed on YouTube. What I need is a dependable solution that can watch roughly 1,000 ads per day on that platform without raising red flags or violating YouTube’s policies. Here is what matters to me: • Every view must register as a complete ad watch on YouTube so the reward platform credits the event. • The process has to run hands-free once it is set up—no daily babysitting on my side. • My personal YouTube account must stay safe. I cannot afford any strikes, bans, or suspicious activity notices. • A basic dashboard or log that shows how many ads were viewed in the last 24 hours is essential so I can verify performance. I am flexible on how you achieve this. ...

ABOUT US We are a small automation business with five working Python services, each running in Docker. The code currently exists in only one place, without version history or a reliable backup. We want to organize it properly in GitHub before building anything new. We are not programmers. Clear, plain-English documentation matters as much as the technical work. SCOPE OF WORK We will provide the source code directly. No production-server access or live credentials are required. You will: Create four private repositories in our GitHub organization—one for each service. Organize each service into a clean, sensible structure. Add the correct .gitignore, dependency files, Docker files, and an . with placeholders. Check for passwords, tokens, API keys, .env files, and other ...

I’m building a responsive web platform that puts an online bookstore—both physical titles and ebooks—at its heart and then layers in a set of everyday utility services. The first release must pair a clean, mobile-first UI with a smooth shopping experience: catalog browsing, advanced search, product detail pages, a full shopping cart, and a wishlist that users can save across devices. Buyers will check out through an integrated payment gateway, pay with an on-site wallet, and earn cashbacks that appear instantly in their account. Order history needs to update in real time, while SMS and WhatsApp push every key status change automatically. Beyond books, the site will let users recharge phones, settle utility bills, book bus seats, and reserve IRCTC train tickets—all ...

I need a fully custom-built business website that goes beyond a simple brochure and includes core e-commerce capabilities: a secure payment gateway and an intuitive product search with robust filtering. I am not looking for a WordPress or Shopify solution—I want clean, maintainable code written from the ground up so I am free of template constraints and monthly platform fees. Key deliverables: • End-to-end design and development of a modern, responsive business site • Seamless payment gateway integration (PCI-compliant, major cards + wallets) • Fast, accurate search and filter functionality for my product catalogue • Admin dashboard where I can add or edit products, prices, and inventory • Deployment to my hosting environment with basic docum...

I want a lightweight, web-based tool that helps me stay on top of project tasks from start to finish. The core of the system is a clean LIST VIEW where I can: • create and assign tasks to specific team members, • set due dates with automatic reminders, and • record quick progress updates that are easy to scan at a glance. If a task changes hands or a deadline shifts, editing should be frictionless and instantly reflected for everyone. I do not need Kanban columns or a full Gantt timeline—just a fast, searchable list that can be filtered by assignee, status, or due date. A straightforward dashboard, email or in-app notifications, and the ability to export data (CSV or similar) would round things out nicely. I’m open to the underlying stack as long as it’...

Our hotel needs a modern, conversion-focused website whose single purpose is to turn visitors into confirmed guests. The site must be built around a fully custom reservation system rather than a plug-in or third-party widget. Key elements I expect from that system: • Real-time availability tied to each room type, so guests never encounter double-booking issues. • Integrated payment gateway for instant, secure card processing. • Automated booking-confirmation emails & WhatsApp messages triggered immediately after payment. • An interactive, filterable room catalogue that showcases each category with photos, rates and key amenities. * To display nearby attractions & popular eateries Beyond the booking engine, the rest of the site should load quickly on ...

I need a focused C# add-in that taps straight into the Autodesk Revit API to automate rebar placement. The goal is simple: with a single command the plug-in should populate beams, columns, and walls with the correct bar sizes, counts, and spacing based on user-defined parameters or templates, saving the manual layout work our team currently performs. Core workflow I have in mind • User selects the structural elements (or the active view) • A settings dialog lets them pick the bar family, cover, spacing rules, and any lap or hook options • The routine then generates the bars, respecting host geometry, covers, and clashes, and updates instantly if the host member changes Acceptance criteria • Written in C# using Revit 2023+ API • Clean, well-commented cod...

I want to launch a complete e-commerce solution that works seamlessly on the web, iOS, and Android. The project begins with a clean, modern UI: intuitive menus, fast product search, and a checkout flow that feels effortless on any screen size. Every page needs to be fully responsive so shoppers who start on desktop can continue on a phone without missing a beat. For the mobile side, I need native-like performance on both iOS and Android, whether you prefer Flutter, React Native, or another cross-platform approach. Push notifications, secure in-app payments, and deep linking should be baked in from day one. On the web, the same feature set must be available—product catalogue, user accounts, wish-lists, reviews, and a robust admin dashboard for inventory, orders, and analytics. Secur...

OBD Calling App + Web Admin Panel – Full Source Code Required I need a developer to build a complete OBD (Outbound Dialer) Calling System for business use. The project must include: - Android App - Web Admin Panel - Backend/API - Database - OBD/Cloud Telephony API Integration - IVR/DTMF Response System - Lead & Customer Management - Telecaller Module - Complete Reports - Notifications - Full editable source code Main Requirement Admin should be able to upload customer mobile numbers through Excel/CSV and run automated outbound voice-call campaigns. The system should: - Automatically call uploaded customers through an approved OBD/cloud telephony provider - Play prerecorded voice messages - Detect answered, busy, no-answer and failed calls - Capture call duration - Capture ...

I need a straightforward system that lets us follow every 5-gallon / 20 L bottle from the moment it leaves our factory until it comes back again. Each container already carries a permanent QR code such as “BTL-000127”, so the job is to capture those scans and turn them into clear, actionable data. Scope of work • Web dashboard – a browser-based control centre where I can see, at a glance, where every bottle is, which customer it is linked to, its full scan history, and any units that are overdue, lost, or marked damaged. • Mobile application – the drivers’ tool for scanning and assigning bottles while they are on the road. This must run on both iOS and Android, work with the phone’s camera QR reader, and allow quick offline capture that sy...

Tôi cần một đoạn script giúp tự động hoá các tác vụ trên website. Trọng tâm là “Automating tasks” nên mã phải gọn, dễ triển khai và chạy ổn định ngay cả trên hosting phổ thông.

I have an online assessment . PALS to take with sections and questions.

I need the daily outbound quota of my registered WhatsApp Business API number lifted from the current 100 k ceiling to the maximum tier Meta allows (ideally “unlimited”). The work concerns sending only; incoming traffic is already handled smoothly. The phone number is a single, fully verified WABA line that sits inside an active Meta Business Manager, and we already run approved message templates and signature‐based authentication on every call to /messages. Your task is to analyse our present setup, determine the quickest compliant route to the top-tier limit, and execute the required steps—whether that involves sending the additional quality/volume signals Meta’s system expects, submitting further documents, coordinating with a BSP, or optimising our existing Clo...

I need an embedded-software specialist who can take my collection of Wi-Fi and LoRaWAN gateways and assorted sensors and knit them into a single, production-ready IoT platform. The job covers the full stack from firmware that runs on the edge devices through to the application layer that users will see. Core capabilities the platform must deliver: • Data collection from every gateway and sensor • Robust device management (on-boarding, remote configuration, OTA updates) • Built-in analytics so I can visualise trends and run simple rules without exporting data elsewhere You’ll be free to recommend languages, embedded RTOS options, and cloud back-ends, provided they reliably handle both Wi-Fi and LoRaWAN traffic and scale cleanly as more hardware is added. De...

I’m building a fully automated rice-mill and need a cross-platform mobile application that lets me observe the plant in real time. The current phase is strictly Monitoring; the framework, however, should be flexible enough to accommodate future Control and Reporting extensions. Core data streams to visualise: • Machine performance (uptime, temperature, speed, etc.) • Production statistics (throughput, yield, rejects) • Energy consumption (per machine and overall) The app must compile for both iOS and Android from a single code base—Flutter, React Native or a comparable toolkit is fine—presenting intuitive dashboards, trend charts and push-alert thresholds. A lightweight cloud back-end (Firebase, AWS, Azure or similar) will collect sensor or PLC data; plea...

I need a small Dolibarr module that lets me attach JPEG images directly to a project report and label every file with its relevant project-stage tag (e.g. Planning, Execution, Handover, etc.). When a user uploads the image, the tag should be chosen from this fixed list so we keep our naming consistent across the ERP. Right now I am undecided about letting users create their own tags. If you can keep the code flexible enough to switch that feature on or off through the module settings, please highlight how you would do it. Key expectations • Seamless upload from the Project card – no separate menu. • Stored files must follow Dolibarr’s standard directory logic so backups keep working. • Tag field visible in the document list and in the file detail pop-up. ...

I already run a working tele-calling suite: one web portal and three Android apps distributed as locally installed APKs. The code is stable, but the original developer has moved on, so I need a parallel copy of the entire stack—web and mobile—where we can add new functionality without touching the production system. After the environment is mirrored, I want two key upgrades: • Call recording built right into the apps, capturing both sides of every conversation, saving securely on the server, and linking each recording to its corresponding call log for easy playback. • A clear analytics & reporting layer that turns raw call data into actionable charts and exportable reports—think totals, durations, agent performance, and conversion metrics viewable on the...

WhatsApp API Setup Freelancer must handle the complete Meta setup, including: Meta Business Portfolio configuration WhatsApp Business Account WhatsApp Business phone number Meta Developer App WhatsApp Cloud API API authentication Webhook Webhook verification Message templates Template variables Production con...

$5-$10. Max for this expert information: EXPERT REQUIRED: POLYMARKET HISTORICAL DATA ARCHITECTURE FOR QUANTCONNECT/LEAN I need an expert to solve one specific problem in my existing Polymarket quantitative trading system. With traditional futures trading, I can obtain large amounts of continuous historical data for the same underlying asset and use QuantConnect/LEAN to perform discovery, backtesting, walk-forward testing, out-of-sample validation, overfitting analysis, parameter optimization, and strategy validation. Polymarket is fundamentally different because it consists of thousands of individual prediction markets that open, evolve, and resolve at different times. My concern is that my current LEAN bridge does not have enough historical Polymarket data in a format that allows it ...

Mam gotowy, wstępnie przygotowany przez Cloud fragment kodu w Pythonie – potrzebuję, abyś szybko przekuł go w działający skrypt automatyzacyjny. Zadaniem skryptu ma być jednoczesne: • zbieranie danych ze wskazanych stron internetowych (kilka prostych źródeł HTTP/HTML), • komunikacja z zewnętrznym API, do którego pozyskane dane będą wysyłane w ustalonym formacie JSON. Kod startowy oraz dostęp do repozytorium, przykładowe endpointy API i krótką specyfikację otrzymasz ode mnie od razu po rozpoczęciu współpracy. Oczekuję, że: • uzupełnisz brakujące moduły / funkcje, • zadbasz o przejrzyste logowanie błędów i solidne obsłużenie wyjątków, • przygotujesz prostą instrukcję uruchomienia (README) wraz z listą wymaganyc...

I need a complete SellHub store built and ready for launch. The site must handle both digital downloads and physical inventory, so the product structure should be organised for licensing files, instant-deliverables as well as shippable items. Please add an initial batch of products.. For payments I’ve settled on Stripe and crypto for checkout, refunds and webhook handling all have to run through Stripe’s latest API version so I can use their dashboard without extra plugins. Discord is a core part of the workflow. Customers should be able to sign in with Discord OAuth2 (user authentication) and, once an order is completed, a purchase-confirmation message must post automatically to a channel I specify (notification system). Keep the code clean so I can later extend it to activi...

I already have an Android Device Policy Controller that locks financed handsets when an EMI is missed, plus a small web dashboard that lets the lending team provision devices and trigger unlocks. The current build is unstable on Android 13, the UI feels dated, and the payment workflow is tied to a gateway we no longer use. I need the entire solution rebuilt and hardened. Core behaviours that must work flawlessly: • Lock the phone the moment a scheduled payment fails. • Allow me to whitelist only basic apps (dialer, messages, payment app) while the device is locked. • Push automatic reminders before the due date and after a failure until settlement. • Capture an e-mandate (eNACH/UPI AutoPay) during onboarding so future EMIs run without user action. The admin portal sho...

## AI-Powered Personalized Exam Preparation — React Native Expo App I have an existing **React Native Expo mobile application** for government/competitive exam preparation and want to integrate an **AI-powered personalized learning system** that analyzes each student's existing exam activity and provides actionable, personalized guidance. ### What I Need Built The AI should use the student's existing data, such as: * Exams/courses attempted * Questions attempted * Correct and incorrect answers * Question-wise performance * Subjects and chapters * Topics/subtopics * Mock test scores * Previous/PYQ performance * Time spent or other available performance metrics * Overall progress and historical performance The system should analyze this data and generate a **personalized...

I’m building a Java-based web application and the very first module I need completed is secure user authentication that relies on two-factor verification rather than the usual single-password flow. The goal is simple but critical: a visitor must be able to register, log in, and re-authenticate using a second factor (TOTP, SMS, or a similar mechanism we agree on) before gaining access to protected routes. The stack is Java on the back-end; I’m comfortable if you lean on frameworks such as Spring Boot and Spring Security, but I’m equally open to lighter solutions provided you can document every step clearly. What matters most is clean, maintainable code and a frictionless developer setup so the rest of the product team can extend your work later. Deliverables I need from ...
