# Senior Full-Stack Developer - Real-Time Squash Scoring & Tournament System ## Project Overview We are a squash club in Denmark with 7 courts and regular tournaments/events. We currently have an online scoring system where referees enter scores live during matches. The basic functionality works well, but the system is unreliable, frequently goes down, and we are heavily dependent on the original developer, who is difficult to reach. We want to build a new, modern, stable and scalable system from scratch, keeping the useful functionality of the current system while significantly improving reliability, administration, tournament management and live presentation. This is not a simple website project. We are looking for an experienced senior full-stack developer with experience in re...

I want to launch an e-commerce website built from the ground up. The site’s main purpose is straightforward: it must let me showcase and sell products online, while giving me a robust way to manage those products behind the scenes. The must-have feature is a full product management system—adding, editing, removing items, tracking inventory, and controlling visibility should all be handled through an intuitive dashboard. If you already have experience wiring this into a modern tech stack (think WordPress + WooCommerce, Shopify custom apps, or a bespoke React / Node build), that will accelerate things. A clean, responsive front end and smooth user experience come next. While standard elements such as the shopping cart or payment gateway could be integrated later, the first mi...

We’re looking for a senior developer to take full technical ownership of an existing live mobile app. The project is already launched, but we’re transitioning away from the current development setup. The first stage will be a full technical takeover: reviewing the existing codebase and architecture, understanding the current setup, completing the handover, and identifying any missing documentation, access, dependencies, or technical issues. The current infrastructure is managed externally, so the project may also require a full migration to new infrastructure under our control, including backend, database, deployment setup, environments, and related services. After the takeover We’re looking for someone to stay involved long-term and handle: * React Native developmen...

Timetable Generator — Automated College Scheduling SaaS A multi-tenant web application that automatically generates conflict-free timetables for colleges and universities using constraint programming. The Problem Creating timetables manually for colleges is a time-consuming, error-prone process. Scheduling conflicts — a teacher in two places at once, a room double-booked, a class group with overlapping lectures — are common and hard to catch manually. The Solution Timetable Generator automates this entire process. College admins simply enter their teachers, courses, rooms, time slots, and class groups — and the system generates a complete, conflict-free timetable in seconds. Tech Stack Backend: Python, FastAPI, SQLAlchemy, Alembic, PostgreSQL Frontend: React, T...

I run a live site and I’d like to bring on a reliable developer who can stay with me month-to-month. Your job is end-to-end: keep what is already online stable, design and ship new user profile pages whenever I request them, and adjust the database architecture so each new feature fits smoothly into production. Here’s what the collaboration will look like: • Monthly cadence, capped at roughly a USD 50 retainer. • You tackle both front-end (React / , Tailwind or similar) and back-end work (API routes, schema updates, deployment tweaks). • When I ask for a new user profile flow—say an extra tab, a fresh settings section, or improved data retrieval—you’ll spec it out, build, test, and push it live. • Code should stay clean and version...

I need a full-stack web application that lets mortgage agents guide their customers through every stage of a loan, end-to-end, inside a single, secure portal. The heart of the system is streamlined application processing, but I also want all supporting tasks—from document intake to final proposal—handled in one place. Key workflow • Agents launch a new file, capture borrower data through dynamic forms, and track progress on a visual timeline of standard mortgage steps. • Borrowers upload required documents to a central document centre; agents can request, flag, and approve items right there. • When the file is complete, the system must assemble the package automatically and submit it to selected banks via email (SMTP or API) with templated cover notes. &...

I need a web-based school management platform whose core mission is to streamline teacher and student interactions. The heart of the build will be two features: • Assignment submissions – teachers create, distribute, collect and grade work online; students upload files or type directly in the portal, with deadline enforcement and automatic time-stamping. • Classroom announcements – an easy, broadcast-style notice board so teachers can post news, resources and reminders that instantly reach every enrolled student, complete with push or email alerts. A clean dashboard for teachers, students and an admin is essential, and the interface must be intuitive on desktop, tablet and mobile. I’m open to the stack—Laravel, Django, Node/React or another modern fram...

My website is already live on a custom HTML / CSS / JS stack, but several areas need attention. Some links land on 404s, a few pages have layout glitches, and certain interactive elements no longer behave as expected. I also have a shortlist of small features that I’d like woven in while you’re under the hood, plus a polish pass on the existing code so everything feels consistent. Here is what success looks like to me: • Every link resolves correctly and no page throws an error. • Layouts are clean, responsive, and visually aligned across modern browsers. • All current functionality works without console errors. • The new features we discuss are integrated seamlessly and documented in the code. You’ll be working directly on raw HTML, CSS, a...

I’m rolling out the first customer-facing release of our U.S. start-up product and need a React specialist who treats testing and quality assurance as the heartbeat of every commit.

Quality first Testing and quality assurance is the priority. I expect functional coverage across modern desktop and mobile browsers, with a mix of manual exploration and any automated suites you judge effective. Unit and component tests must guard critical business logic, and every sprint should close with a concise test plan plus a clear defect ...

I need a full-stack developer to build a SaaS-ready CRM on the MERN stack that can be offered to multiple companies from a single codebase while keeping every tenant’s data strictly segregated. Core features are: • Robust reporting and analytics dashboards drawn from each tenant’s own records only • Email-and-password authentication (JWT sessions are fine) • Payment-gateway integration so each company can upgrade or renew within the app Beyond those basics, the usual CRUD around contacts, deals, and activities can follow standard patterns, but the multitenancy layer and the analytics engine must be rock-solid.

The key requirement is a set of interactive elements— Here’s what I need from you: • Build the front-end so that every animation is consistent with the Claude design language I’ll provide (colour palette, spacing, motion principles). • Wire it to Sanity Studio so I can update copy and images myself. • Handle deployment to Vercel and leave me with a clear hand-off guide covering environment variables, build commands, and any Visual Basic functions or helpers you write.

I have already taken Flyenzo from concept to a working end-to-end flight booking flow using 16 with the App Router, TypeScript, Neon Postgres via Drizzle ORM, Redis, Stripe, and Clerk auth. Search, Stripe Checkout, PNR generation, printable e-tickets, and online check-in are live and stable. What I need now is focused, production-ready work on three areas that matter most to travellers and to the business: 1. Live cabin map The current map renders seats and respects my Redis Lua seat-lock script, but I want smoother real-time updates across multiple sessions, optimistic UI during seat selection, and graceful fallback in local development when Redis is not available. 2. Ancillary add-ons Meal options, lounge access, and priority boarding must be selectable in-flow, priced dynamicall...

I want to launch a web-based EMR portal whose single, non-negotiable focus is appointment scheduling. Patients must be able to create an account with a straightforward email login and then pick an open slot on any doctor’s calendar without staff intervention. Real-time availability matters; once a slot is reserved, nobody else should see it. On the clinic side, I need a clean dashboard where staff can add doctors, set or change clinic hours, block time for meetings, and track upcoming visits. Rescheduling or cancelling should update every view instantly so we never double-book. Automatic confirmation emails after each booking are essential, but SMS or other reminder channels can wait until a later phase. I’m flexible on the tech stack—Laravel, Django, Node/React, or ano...

I need a seasoned MERN developer who can take a business idea and turn it into a fully working, production-ready web platform. This is far beyond a simple CRUD site—I’m aiming for an end-to-end system that automates internal workflows, stores and processes data efficiently, and delivers real-time dashboards my team can rely on every day. Here’s what the work looks like: • React will drive a responsive, component-based interface that feels fast on both desktop and mobile. • Node.js with (or a comparable framework you prefer) will power a secure REST or GraphQL API, built with clear layering and strong typing where appropriate. • MongoDB will serve as the primary data store; I need well-designed schemas, indexing strategies, and aggregation pipelines ...

I’m ready to give my HR-tech platform a modern, responsive interface and need a front-end specialist to make it happen. The server side already handles user authentication, database management and a full REST/GraphQL API, so your focus will be the user experience—clean, fast and accessible on desktop and mobile. To help me choose quickly, share links to past work that best shows: • production-ready UIs you built yourself • how you integrated with authentication and dynamic data • performance or accessibility wins you’re proud of If you’re comfortable with React (hooks, Redux or Context), TypeScript and modern CSS, you’ll feel right at home. Vue or Angular expertise works too—as long as it stays modular and testable. Once we agr...

I want to launch a web-based colour-prediction game where visitors can predict the next colour, place their bets in real time and chat with one another while the round is running. The flow should feel instant—think WebSocket-style updates—so every wager, result reveal and chat message lands without a page refresh. The entire experience must be responsive and work just as smoothly on phones as it does on desktop. An equally important piece is the back-office. I need a password-protected admin panel that lets me: • add, suspend or edit users; • track game statistics round by round, including profit/loss and player participation; • review, approve, void or refund individual bets. The front-end framework is flexible—as long as performance and code qua...
