    I’m ready to launch a niche marketplace where people can buy and sell live one-on-one skills.

    I’m building a mobile-only app that needs a real-time text chat backend dedicated to one-on-one conversations. The goal is a lightweight, low-latency server that can authenticate users, deliver messages instantly, store chat history, and scale as the user base grows—all without the overhead of group or public room logic. I’m open to proven stacks such as Node.js with WebSocket/, Go with gRPC, or an equivalent solution that plays nicely with iOS and Android clients. End-to-end encryption, push-notification hooks (FCM / APNs), and a RESTful or GraphQL API for ancillary data are highly desirable.

The core challenge is two-fold: High-Volume API Integration: We need a robust backend capable of handling thousands of concurrent requests from enterprise-level partners. The system must process transaction data, trigger fulfillment requests, and maintain 100% data integrity. The Transparency Layer: Our unique value proposition is verifiable proof. You must build a database and front-end dashboard that stores and serves geotagged data (GPS coordinat...

    I’m planning an interactive, data-structures-and-algorithms-focused coding duel platform and I need a crystal-clear design and architecture proposal before any code is written. The end product must feel like a learning arena first and a competition second, so every technical choice has to support quick feedback, fairness and easy-to-follow analytics for students. Core experience to address The platform will present the same DSA question to two users simultaneously, lock them into a fixed countdown and stream their code through a real-time execution engine so they can see results (compile errors, test-case pass/fail, runtime, memory) without refreshing. While live chat or leaderboards may appear later, this first proposal must concentrate on that real-time duel loop and the backend...

    I’m midway through a software development project and now need to fold in a fully-fledged user authentication layer. The current codebase is stable and organised; what’s missing are the sign-up, log-in, password reset, and basic role-based access controls that will make the product production-ready. You’ll be working against an existing Git repo. I’ll grant access and walk you through the structure so you can slot your changes in cleanly rather than bolting them on. I’m open to the usual approaches—JWT sessions, OAuth, or any secure flavour you’re most comfortable with—as long as the solution is standards-compliant and easy for another developer to pick up later. Deliverables • Registration, log-in, log-out, password reset flows ...

    Three finished Android apps are ready for their final enhancement: integrating a hosting layer so user data and media can live on a reliable back-end instead of locally on the device. All UI assets, icons, and existing source code are packaged and waiting in the repository; the work now is purely feature addition, not bug fixing or UI tweaks. Scope of work • Choose or configure a hosting solution (Firebase, AWS, or any lightweight VPS—whichever fits best). • Wire the back-end to each app so login, uploads, and simple read/write actions pass through tested API calls. • Update the project settings, build files, and pro-guard rules where needed. • Provide clear build instructions and a short “read-me” detailing endpoints, keys, and deployment ste...

    Hello, We are using Zoho Books (UAE VAT module enabled) for both B2C and B2B invoicing. Currently, each invoice contains multiple services (often 10–15+), and each service consists of: Government fees (VAT exempt) Service/processing charges (VAT @ 5%) Typing or administrative charges (VAT @ 5%) Our challenge is invoice presentation. If each component is shown as a separate line item, the invoice becomes too long and difficult for customers to read. Desired outcome: We want the invoice to display a summarized table with limited rows, while still maintaining correct VAT treatment and accounting accuracy in Zoho Books. Specifically, we would like to explore whether customization (Deluge + template customization) can achieve the following: A summarized invoice table with grouped...

    I need a complete business website built from scratch and taken all the way to live deployment. The project is strictly a website development job, not an app, and the finished site will present my services clearly while giving visitors an easy way to reach me. Core requirements • A clean, responsive service listing section so potential clients can scan what I offer at a glance. • A secure, spam-protected contact form that routes messages straight to my business inbox. Everything else—framework, CMS, or custom code—is flexible. Feel free to propose the stack you work fastest with, whether that’s a React / Node.js setup, a Django build, or a PHP framework like Laravel. What matters is that the final result loads quickly, follows best practices in HTML5, CSS3...

    API-First Trust System MVP

    I need a backend engineer to turn my spec into an MVP that exposes a clean, API-first trust and reputation service for autonomous AI agents. The entire product lives server-side—no front-end work at all—so every feature must be reachable through intuitive, well-documented endpoints. Core requirements • Stack: your choice of FastAPI (Python) or Node (TypeScript), backed by Postgres, containerised with Docker, and wired to Stripe for billing events. • Auth: simple, robust API Key flow; keys must be generated, stored, and validated on every request. • Scoring logic: compute each agent’s trust score solely from its interaction history, according to the formulas in the spec. Performance metrics or direct user feedback are outside this first iteration. ...
