I have already designed and built most of C’8 – Coordinate, an open-source aid-coordination platform you can preview here: https://www.c8coordinate.com. The interface is in place; where I need help is on the backend. Your main task will be to implement and refine our internal APIs so the existing frontend can finally talk to the server smoothly. You will be shaping the data flow between the client app and the database layer: creating clean, well-documented endpoints, handling authentication hooks already stub-built, ensuring robust validation, and returning responses the UI expects. I am using a Git-based workflow and will grant access to the repo plus a small set of Postman collections that describe the calls I need. Key deliverables • Fully working internal API endpo...

I need an experienced developer to turn a fresh idea into fully-functional software. I’ve marked this as a software development project, but I’m still deciding whether the final build should be a web, mobile, or desktop application.

Ich plane eine App für ein Debian-basiertes Touchscreen-Terminal. Die Anwendung soll eine interaktive Steuerung ermöglichen und dabei hauptsächlich Textinformationen anzeigen. Über eine gesicherte Verbindung muss sie fortlaufend mit einem Backend-Server bzw. einer Cloud-API kommunizieren, um Befehle zu senden, Statusmeldungen zu empfangen und Konfigurationsdaten zu synchronisieren. Was ich mir vorstelle • Eine schlanke Desktop-Anwendung (kein reines Kommandozeilentool), optimiert für Touch-Eingaben unter Debian/Linux. • Klare, gut lesbare Oberflächen in Vollbild-Kiosk-Manier. • Reibungslose Kommunikation zu meinem bestehenden REST- oder WebSocket-Backend – Latenzarm und fehlertolerant. • Automatische Wiederverbindung bei Netz...

I’m building an Android application that must verify users through SMS-based one-time passwords. I already have the UI in place; what I need is a clean, reusable module that will: • Trigger an SMS-OTP request via a lightweight REST API you create (any language or framework you’re comfortable with). • Auto-read the incoming OTP on the device using Google’s SMS Retriever/User Consent API so the user never has to type it. • Enforce a resend option (configurable delay), show a visible countdown timer while the code is valid, and lock the flow after a defined number of failed attempts. Deliverables: 1. Android source (Kotlin or Java) wrapped as a library or clearly separated package. 2. Server-side endpoint(s) that generate and dispatch the SMS, plus s...

I need an experienced Frappe/ERPNext developer to build a dedicated laboratory-management module for my current ERPNext installation. The goal is to handle sample intake, testing workflows, results approval, and inventory usage while also letting me monitor budgets and run simple forecasting on consumables and costs. You will create a standalone app that plugs cleanly into ERPNext, defining all necessary DocTypes, role-based permissions, and custom reports. Budgeting and Forecasting should be woven into the module so that each lab project or test batch shows projected versus actual spend and upcoming resource requirements. Core tech will be the usual stack—Python, Frappe framework, ERPNext API hooks, MariaDB, and a little client-side JavaScript where it improves the UI. I already h...

I run a high-end joinery company in Sydney and I need a expert to translate our end-to-end manufacturing and installation flow into a single, intuitive workspace.

I’m working with the open-source HandHeldLegend/hoja-device-fw project that targets the Raspberry Pi RP2040. I already have a short code snippet that defines a frame-perfect macro intended for gaming cheats: when the physical Y button is pressed the firmware must • hold Y for exactly 16 ms (one frame), • release it for 16 ms, • then push the Right Analog/C-Stick fully downward for another 16 ms. Nothing else in the firmware should change. What I need from you 1. Pull the repository, drop the snippet into the correct input pipeline so the macro cleanly intercepts the Y press without introducing latency or breaking other inputs. 2. Compile the project in a proven RP2040/Pico SDK environment (CMake, gcc-arm-none-eabi, etc.) and return a ready-to-flash .uf2 i...

Necesito un editor protegido que me permita conectar por OBD a camiones Volvo y realizar programación remota completa de cualquier módulo. El objetivo es poder actualizar software y personalizar configuraciones sin importar la ciudad donde se encuentre el vehículo, abarcando los sistemas de motor, transmisión y frenos. El flujo ideal es sencillo: yo me conecto al camión mediante una interfaz OBD-II, abro tu herramienta, selecciono el módulo y cargo o modifico el firmware/ parámetros; todo lo demás (validaciones, seguridad, checksum, desbloqueo, etc.) debe quedar cubierto internamente por la aplicación para que el proceso sea fiable y a prueba de errores.

I’m gearing up to launch a new software product in the technology space and need focused, data-driven insight to choose the right markets and channels. The core of this engagement is market research—specifically a market entry strategy that will let me validate the software, understand customer expectations, and position the product for sustained growth. Here’s what I need from you: • A clear profile of the addressable market: size, growth rate, and trends that could affect adoption. • Competitive mapping that highlights key players, their pricing models, feature sets, and any whitespace we can exploit. • Target-customer segmentation, buyer personas, and the pain points that resonate most with each group. • Recommended go-to-market options (dir...

I want to land a fully remote position in the technology space and need expert help to make it happen quickly and efficiently. My background spans several areas of tech, so I’m flexible on the exact role—software development, data-focused work, or even IT support are all on the table—but the position must be 100 % remote. Here’s what I’d like from you: • A targeted, up-to-date list of genuine remote tech openings that match my profile and salary expectations. • Optimised versions of my résumé and LinkedIn profile tailored to those roles. • One reusable cover-letter template plus brief, role-specific tweaks where needed. • Clear application tracking so I always know submission dates, follow-up timelines, and interview ...

I need my existing Tally ERP 9 setup fine-tuned so the inventory module truly matches the way we track stock on a day-to-day basis. This means altering item classifications, vouchers, and stock movement screens so they reflect our real workflow instead of the default structure. You’ll be working directly on our live data file (a recent backup can be provided first) and should be comfortable writing and integrating TDL to: • Add or modify inventory fields and calculations • Adjust voucher layouts for quicker data entry • Generate accurate, on-demand stock valuation and movement reports that align with our accounting policies I’m interested in seeing what you’ve already achieved for other companies—screenshots, brief case studies, or demo video...

I’m looking for a freelancer to build a clean, high-quality website for my trading card business, PokeVaultHTX. I want the website to be a smooth, modern, single-page scrolling website instead of having multiple separate pages right away. The goal is to have everything flow on one main homepage, with each section acting almost like a clickable or expandable menu. The website should feel professional, trustworthy, easy to update, and simple for customers to use on both desktop and mobile. There can be a dropdown or hamburger menu in the top right or top left corner, but the menu should mainly jump users to sections on the same page instead of opening a bunch of separate pages. The main website sections should include: Home / Logo / Intro Ever-Changing Inventory Sell / Trade With ...

I need a small but robust utility that runs on Nintendo Switch 2 and helps players squeeze the best possible performance out of their games. The core focus is performance optimisation: analysing in-game behaviour, identifying bottlenecks on the fly and applying smart tweaks so titles load faster, maintain steadier frame rates and feel more responsive. What I picture is a lightweight overlay or background service written in C/C++ (or another language supported by the official Switch 2 SDK) that: • profiles CPU, GPU and memory usage in real time, • applies dynamic setting adjustments or recommends the ideal presets, and • logs before/after metrics so users can clearly see the gains. SDK-compliant code, clean architecture, and clear developer documentation are es...

I want to master the very basics of Python, starting from the ground up. I am a complete beginner, so every concept—from installing Python 3.x and choosing an editor such as VS Code or Jupyter Notebook, to writing my first “Hello World” script—needs to be explained in plain language. The format I’m after is live, one-on-one sessions held online. Screen-sharing, real-time coding, and plenty of room for questions are essential because they let me see the workflow in action and practice immediately. We can agree on a weekly schedule that fits us both, but consistency is key. By the end of the training I should comfortably: • understand variables, data types, and basic operators • write and use conditions, loops, and simple functions • read ...

I need a straightforward panel that lets me broadcast WhatsApp messages in bulk without getting lost in complicated menus. The core task is simple: I upload a contact file (CSV or Excel), type or paste my message, attach any images or videos I like, hit send, and the system delivers everything quickly and reliably. Key needs • Message broadcasting is the main workflow—no chatbot or drip-campaign logic required. • Full multimedia support: photos and videos must go out exactly as they look in WhatsApp. • Contact management stays manual, so an intuitive import/export screen is essential (drag-and-drop or browse-to-upload is fine). Deliverables 1. Web-based or desktop panel, fully functional on delivery. 2. Source code plus a brief setup guide so I can rein...

I have an existing Node.js/Express application already deployed (Render backend + Hostinger frontend). I need an experienced Meta/WhatsApp Cloud API developer to complete the production setup and integrate WhatsApp messaging. Current Status Node.js backend is already developed.

I have a steady stream of recruiter, technical and HR screening calls coming up and need an experienced web-development professional who can step in for me on each one. The conversations cover full-stack topics, most often in Java, C#, Python and React Native, with occasional .NET questions. Your task is simple: join every scheduled call on my behalf, answer confidently, and carry the discussion through to the next stage until a formal offer is issued in my name. You should be able to speak to at least six or seven years of end-to-end web-development experience, explain project architecture decisions, discuss common design patterns, and handle soft-skill questions during HR screenings just as comfortably as the technical deep dives. Reliable English fluency and a calm, professional pho...

I need a small program that quietly runs on our server and keeps the freight information on our public site completely in-sync with a local source folder. Every ten minutes it should: • scan the designated directory, • upload any new or changed text files, • remove any text files that were deleted from the directory, so the web content always mirrors what we have internally. The directory path will be configurable; everything in that folder is considered authoritative. Reliability and low overhead are far more important than fancy visuals, so feel free to use a lightweight approach—Python with watchdog and an FTP/SFTP library, a PHP cron job, a Node script, or another solution you prefer—as long as it can run unattended on a typical Linux hosting environ...

Please refer attahced document.

I need a small, accurate program that accepts two medium-resolution JPEG photographs of a finished metal assembly and automatically presents them side-by-side, with every visual difference clearly highlighted on the right-hand image. The purpose is simple: help our fabrication team spot mis-welds, missing brackets, or other subtle manufacturing deviations without having to inspect the parts manually. Here is what matters most to me: 1. The tool must read standard JPEGs shot between 720p and 1080p—you can assume consistent lighting but plenty of reflections and shiny edges typical of stainless steel. 2. Output should be a single composite image (or screen) that shows both originals next to each other; regions that differ are accented visually so a technician can locate them in second...

I already have a working codebase, but it’s missing one key feature. I’ll share the repository as soon as we start; your first step will be to review the current structure, understand how the components fit together, and then build the new functionality so it blends naturally with the existing logic. Clean, well-commented code and no regressions are essential. Please make sure unit or integration tests cover the new paths and that your changes don’t break any current behavior. Once the feature is in place, a short note explaining the new modules, configuration updates, and how to trigger or disable the feature will be plenty. If you’re comfortable jumping into someone else’s code and extending it confidently, I’m ready to get started right away.

I need a clean, well-commented Python script that can place Equity orders on the NSE through my broker’s REST API. The program must support three order types—Market, Limit, and Stop-loss—and switch between them with a simple function call or flag. Key expectations • Handle authentication, session renewal, and basic error catching so an interrupted connection will not leave an order half-sent. • Clearly separate configuration (API keys, tokens, quantity, symbol) from the core logic so I can reuse the same code across multiple accounts. • Return the order ID and status in real time, ideally as both terminal output and a lightweight log file for later reconciliation. Deliverables 1. A single .py file (or small module set) ready to run. 2. A sho...

I’m working through the hard-level section on LeetCode and would like clean, well-commented Python solutions that I can study and learn from. The focus is on algorithmic challenges, advanced data-structure manipulation, and occasional system-design–style questions that appear in LeetCode’s “hard” catalog.

I need an Android APK that predicts Aviator game outcomes and automatically references my Telegram channel for updates and community support. The heart of the app must be a rule-based prediction engine built around real-time market analysis and indicators I will supply. No machine-learning black boxes—every rule should be transparent so I can tweak thresholds later. Alongside the APK, I also want a lightweight key-generator desktop tool (Windows preferred) that produces unique activation keys. On first launch, the APK should prompt for one of these keys, validate it locally, then unlock full functionality. This licensing step is crucial for controlling distribution. Deliverables • Signed Aviator prediction APK with integrated Telegram deep-link (I’ll provide the channe...

I have just completed an in-place migration of Sonatype Nexus Repository Manager from 3.70 to 3.93. The service is online and the UI loads normally, yet every developer now receives “permission denied” messages when they try to pull from or publish to our Maven, npm, and Docker repositories. At this point I am not entirely sure whether the problem lies in role mappings, privilege inheritance, or another post-upgrade quirk, so I need someone with deep Nexus experience to jump in, diagnose the root cause, and restore seamless access. What I expect you to do: • Review and correct all roles, privileges, and repository targets so authenticated users can reach the appropriate Maven, npm, and Docker endpoints. • Validate access locally from a clean workstation by per...

I have a diverse range of trucks, including Volvo, Kenworth, Freightliner, and others, that need full electronic calibration, adaptation, and DEF system cancellation. All work must target each specific platform's ECU architecture, parameter programming, and SCR/DEF logic—so please be completely comfortable with multiple truck manufacturers before you respond. What I expect from you: • A safe, tested calibration file (or remote-session process) that eliminates DEF usage while keeping all other engine protections intact. • Clear, step-by-step instructions for flashing the ECU, including any license keys, interface cables, or software versions required. • A brief post-flash check procedure so my technicians can confirm everything is working and no fault codes remain...
