I am building a green-field fraud-detection platform and need an experienced back-end engineer to own the server-side work for the next three months. The stack is .NET (C#), PostgreSQL, and Redis; a separate team will handle the React front end, so your focus stays firmly on the APIs, data layer, and real-time processing pipeline. What the engagement looks like You will translate our detection logic into clean, well-tested C# services, design the relational schema in PostgreSQL, and use Redis for low-latency caching and message queues. Because the app is completely standalone, there are no third-party or legacy integrations to worry about—every decision you make will directly shape the core product. Key expectations • Produce readable, documented code that passes automated...

I have an exploratory project that must be online and demo-ready in just two days. The theme is “Roommate work-based,” but in my case the end-users are families who share a home and want to run it like a smooth household. The core features I need working are: • Task management – create, assign, edit and mark chores complete. • Scheduling – a shared calendar or timeline so everyone sees who does what, when. • Communication – lightweight in-app chat or comment threads tied to each task. A clean, responsive interface is essential so parents and kids can open it from phones, tablets or a laptop without confusion. Real-time updates ( / Firebase style) would be ideal, yet a quick AJAX refresh loop is acceptable if speed is a concern. Please del...

The project involves designing and building an end-to-end technical solution completely from scratch. I need everything covered, from early-stage consultation and requirements gathering through architecture, coding, testing, and deployment. Because the exact discipline—software, data, or support tooling—remains open, I welcome recommendations on the most appropriate tech stack and workflow once you understand the business problem in more detail. Key deliverables • A fully functional, tested solution that meets the agreed-upon requirements • Clean, well-commented source code stored in a version-control repository (Git) • Concise technical documentation: setup instructions, user guide, and maintenance notes • A brief hand-over session (video or writte...

I’m planning to roll out a new Android application built with Flutter and supported by a Laravel-powered REST API. All code should be production-ready, well-structured, and clearly commented so my in-house team can maintain it after hand-over. The job covers: • Setting up the Laravel backend (auth, role management, and any additional endpoints we agree on). • Building the Android client in Flutter, fully wired to the API. • Solid error handling, state management, and responsive UI that feels fast on a wide range of devices. • Clean Git workflow: feature branches, readable commits, and a short onboarding note explaining how to spin the project up locally. Please highlight any similar apps you’ve shipped with Flutter plus Laravel, your preferred state-...

I have spent the last eighteen months bringing India’s first live-commerce marketplace to life and already have roughly 60 % of the product in production. The next phase is scaling fast, so I’m opening equity-based founding seats for developers who want to grow a large startup alongside me rather than take on a short contract. Here’s where you could plug in right away: • Flutter – 3–4 years building production apps, comfortable with BLoC state management • React.js – 2 + years crafting modern, component-driven UIs • Node.js – 2 + years in scalable back-end work; TypeScript and PostgreSQL experience is a welcome bonus Day to day you’ll ship features, own architecture decisions, and shape product direction with a tight f...

I plan to launch a full-featured social-networking web application and need a skilled software developer to turn the concept into a secure, scalable product. This is pure software development: no mobile or desktop versions for now, just a modern, browser-based experience that works smoothly on both desktop and mobile screens. Core scope The platform should let users sign up, create profiles, post updates, follow one another, and exchange real-time messages. A clean, responsive UI plus a robust back-end API are essential. I’m open to the stack you prefer—React, Vue, Angular, or similar on the front end, and Node, Django, Laravel, or equivalent on the server—as long as the code is well-structured, well-documented, and ready for future scaling. Key deliverables • Comp...

We are looking for a freelancer with strong experience in Voice AI, API integrations, and automation to help extend our existing AI agent setup. Project Overview: We already have avatars deployed through ElevenLabs and HeyGen on one of our websites. The current setup allows users to interact with AI voice and video agents, and now we need to add email functionality. We currently use HL (HighLevel) as part of our CRM workflow, so familiarity with CRM connectivity, automation, and trigger-based actions is important. Scope of Work: • Integrate email capability into the existing voice and video AI agent workflow. • Enable the agent to capture a user’s email address during conversation. • Allow the agent to automatically send requested documents, links, or information t...

I am expanding my in-house ERP and need a clean, well-documented API for several custom modules that sit alongside our existing inventory, HR, and accounting areas. The current system already exposes sandbox and production endpoints with separate keys, so your work must plug neatly into that dual-environment pattern. Core requirement: the new endpoints must handle user authentication using an API Key strategy. If you want to architect them so we can add OAuth2 or JWT later, that future-proofing is welcome, but for now the live build must rely only on API Keys. You will create the APIs and test the endpoints, then hand over concise documentation that shows other developers exactly how to hit sandbox versus production, obtain or rotate keys, and handle typical error responses. Deliverable...

I’m ready to give our existing site a functional facelift. The priority is to eliminate the handful of lingering bugs that interrupt the current user flow, then roll out a cleaner, more robust product-and-service showcase so visitors can explore what we offer without friction. Once stability is restored, I need Razorpay woven into the checkout. This means creating a seamless, SSL-secure payment experience that includes order confirmation, error handling, and clear transaction feedback on both desktop and mobile. Key deliverables: • Squash all reported front-end and back-end bugs (I’ll share the ticket list). • Rework the product/service pages to highlight features, pricing, and media in a modern, responsive layout. • Integrate Razorpay, test the full paym...

I have an existing Task Management System built with Java, MySQL, HTML, CSS and JavaScript. It already handles user registration, task creation, updates and progress tracking, but I now need a round of polishing and growth. Improvements I want right away involve • giving the interface a cleaner, more responsive look and feel, • tightening performance so pages load quickly even with a large task list, and • hardening security around authentication, role-based access and data storage. On top of that, I’d like to expand the product with new functionality—think calendar-style views, smart notifications or whatever you propose—and connect it with popular collaboration tools (for example Slack, Microsoft Teams or Google services). If you have ideas for se...

For my final-semester project I need a fully functional restaurant website that feels modern and clean from the first click. The core pages should showcase the menu in an appetising, easy-to-navigate layout, collect customer reviews that can be moderated from a simple back-end, and allow visitors to book a table through an online reservation form (email notification is enough; full booking engines are welcome if you already have one). Because this is an academic submission, clear documentation is almost as important as the code itself: a brief read-me explaining folder structure, any frameworks or libraries used, and instructions to spin the project up locally will be required with the final hand-off. Responsive behaviour across common breakpoints is essential so I can demo it on both des...

I need an application that lets me remotely control my industrial equipment in the sense of keeping an eye on its live performance data from anywhere. The machinery is already fitted with basic IoT-ready sensors; what is missing is the cloud-to-device bridge and a clean user interface where I can watch throughput, temperature, and fault codes in real time. Here is the flow I have in mind: • Edge device pushes sensor readings via cellular data to a secure backend (MQTT or HTTPS—use what you are most comfortable with). • Backend stores, normalises, and exposes that data through an API. • A web or mobile dashboard pulls the feed and displays key performance metrics with alerts when values drift outside preset thresholds. That monitoring dashboard is the first miles...

I need a web-based administrative panel that lets me oversee several IPv4 proxy servers running 3Proxy from one place. The panel should: • Auto-configure new or rebuilt servers, applying 3Proxy settings and firewall rules without manual SSH work. • Push software updates, configuration edits, and security patches to every connected host remotely. • Expose a documented RESTful API so other systems can create, suspend, rotate, or delete proxies programmatically. • Support multiple user roles—at minimum Admin plus one or more limited roles—with a clean permissions model. • Display real-time status (online/offline, traffic, errors) and basic analytics for each proxy. A straightforward, responsive UI is essential; think login, dashboard, server list...

I want to replace the current iframe workflow on with a full, white-label integration of ’s embedded-finance lending platform. The goal is to control every stage of the loan journey in-house—from application to credit decisioning to final approval—without ever sending our borrowers off-site. Scope of work • Connect and authenticate the complete API suite, including endpoints for the loan application form, automated credit checks, and back-office approval management. • Build a clean, mobile-responsive front end that puts ease of use first; I’m open to switching our WordPress theme or using a headless approach if that delivers the best UX. • Integrate payment gateway support so approved borrowers can draw down and repay directly through our por...

I’m building a real-time, two-way translator dedicated to business calls and need an expert who can take it from concept to a working product. The first release must handle English ⇄ Spanish flawlessly, converting speech to text, translating it, then rendering clear synthesized speech back to both parties with minimal latency. Compatibility is non-negotiable: the same core engine has to run inside a web browser, a mobile app (iOS and Android), and a lightweight desktop client. I value reusable backend services—WebRTC for voice transport, a robust ASR + NMT pipeline (DeepSpeech, Whisper, or similar paired with a proven translation model), and near real-time TTS. Security, call recording toggles, and an admin dashboard for basic analytics should round out the feature set. I...

I need a robust yet lightweight script that connects to a specific online-auction platform and captures every live bid event. For each event I must see two fields only—the current bid price and the bidder’s (party) name—and have them appear automatically inside an Excel file as the auction progresses. Near-instant updates (a few seconds at most) are essential so I can analyse bidding behaviour on the fly. There is a range of price ie betwenn L1 and H1. I want to know which parties are bidding at which prices and their last bid price. The site uses dynamic content so the solution will likely rely on Python with Selenium, Playwright, or direct WebSocket/API interception—whichever achieves stable real-time capture without breaching the site’s terms. Please build...

I need a complete build of both a public-facing website and a companion web application. Both properties must share the same brand identity, load quickly on mobile and desktop, and be easy for me to maintain after launch. Here’s what I expect: • A clean, responsive UI that works flawlessly in all modern browsers. • A secure, well-documented back end that can scale as traffic grows. • Deployment to my preferred hosting or cloud account, with automated CI/CD if practical. • Clear hand-over: source code in a Git repository, instructions for local setup, and a short walkthrough video or call. Acceptance criteria • All core pages render without visual defects at 320 px, 768 px, and 1440 px widths. • Lighthouse performance score of 90+ on mobile. • No c...

Project Overview I am building an AI astrology chatbot that gives readings based on a user’s natal chart, solar return chart, and lunar return chart. Right now the chatbot depends on users manually going to Astro-Seek, generating chart exports, and pasting those exports into the chat. I want to replace that process with an automated backend calculation engine that generates the chart data directly and passes it into my OpenAI chatbot. This project is not a full astrology app with a GUI. The chatbot is the user-facing interface. What I need built is the chart calculation layer that collects the required birth and return information, calculates the charts accurately, and outputs the chart data in a format my AI system can use. Core Workflow When a user starts the chatbot, the syst...

I already have an HRIS web application live, but several core pieces still need to be taken from “mostly there” to production-ready.

Supported transactions The platform must seamlessly handle buying and selling of...

I’m looking for someone who already knows their way around the Whop marketplace and its API to take my existing Base44 app and get it live for purchase. The focus is purely on functionality—no user-data migration and no design overhaul—just make sure the app installs smoothly on Whop and that every paid feature unlocks correctly once a customer buys. You will need to: • Package and upload the current build to Whop • Hook up licensing / entitlement so buyers instantly gain access • Configure pricing tiers and the storefront listing • Test checkout flows end-to-end and confirm activation works I don’t have any integration documentation, so I’ll rely on your experience to bridge Base44’s code with Whop’s requirements and to...

I’m building a web platform inspired by Astrotalk, but aimed at a different audience. The core of the site is a real-time Live Chat system that lets users connect with experts through text messaging, voice calls, and video calls. Alongside the interactive sessions, I want a clearly organized tutorials section so visitors can pick up essential knowledge on their own before reaching out to a specialist. You’ll take the project from concept to launch: designing an intuitive UI, developing a responsive front-end, wiring up a secure back-end with user authentication, and integrating scalable chat technology (WebRTC, , Twilio, Agora, or a similar stack). An admin dashboard for session monitoring, basic analytics, and space for future payment gateway integration should be included. ...
