Job Success
Kharkiv, Ukraine - 9:29 pm local time
Part of a full-cycle delivery team - on Upwork since Sep 2010, 14 years in, 300+ contracts shipped, $700K+ earned, 100% Job Success, Top Rated. You get one developer who owns the whole system, plus an agency bench behind her.
💡 Hiring a full stack developer should not mean hiring a React developer and a Node developer in one body. The value is connection: I design how React, the Node.js backend, the database, and business logic move together from day one, so the front end never guesses what the backend means and the backend never returns data the front end does not use. Across 150+ products, that is what keeps React and Node from drifting apart.
🎯 WHAT YOU GET
➜ One accountable full stack developer who scopes honestly, gives a realistic estimate, and ships production-ready code - not two separate implementations stitched together.
➜ A web developer and backend developer in one: I diagnose and fix root causes (slow Node endpoints, CORS and auth errors, dropped env vars, broken React + Node integration), optimize performance, and deliver seamless integration.
➜ A team behind me. If the project grows past one developer, we scale without handing you off to strangers (19,765 hours of high-quality coding delivered).
➜ SaaS: multi-tenant architecture, billing and subscription logic, admin tools, webhook handling, auth and permissions - built for growth in e-learning, real estate, healthcare, fintech, and mobility.
➜ Marketplaces: Stripe Connect flows, booking and availability logic, operator dashboards, multi-role permissions, and complex search, designed as one workflow (buyer, seller, payments, operations).
➜ Backend developer work: REST API design, Express and NestJS services, PostgreSQL and MongoDB data modeling, Redis, event-driven and serverless functions, AWS and Vercel deploys.
➜ Existing codebases: I audit for stability, performance, and code quality, then make step-by-step improvements - no rebuild unless it is truly necessary.
➜ MVPs: a typical V1 ships in 5-6 weeks. One early build I helped ship went on to raise $3M.
➜ Front end: I turn UX designer handoffs into pixel-accurate, responsive UI - React Query strategy, shared TypeScript types, and state that matches the API.
🤖 I use AI coding tools the right way: faster scaffolding, migration prep, and reviews, while architecture, security, data modeling, and API contracts stay human-judged. As a JavaScript developer and software developer at core, I also take python developer work for backend services or data scripts when a project needs it.
🧩 Stack: React, Node.js (nodejs), TypeScript, Express, NestJS, PostgreSQL, MongoDB, Redis, Stripe, AWS, Vercel, Docker, CI/CD.
📊 14 years on Upwork ▪ 300+ contracts ▪ $700K+ earned ▪ 100% Job Success ▪ Top Rated ▪ 150+ products live ▪ 50+ countries ▪ 5,000+ end users on delivered platforms ▪ one MVP scaled to a $3M raise.
Roles I take: full stack developer, full stack web developer, react developer, node developer, nodejs developer, backend developer, javascript developer, web developer, software developer, full stack react node developer.
📩 Need a full stack developer for a SaaS platform, marketplace, custom web app, or MVP -- or a backend developer to fix, optimize, and ship an existing React + Node system? Send a message with what you are building and I will give you a direct, practical view of what is involved, fixed-price or hourly.
