Most developers write code. I ship features that actually work under real users and don't fall apart the first time someone hits an edge case you didn't think to test for. Because when a feature ships late, you lose momentum. When it breaks in production, you lose trust. When the codebase turns into something no one wants to touch, you end up paying for it every sprint after. That's the gap I fill. full-stack JavaScript development built to be extended, not patched. What I build: - SaaS & MVP Development: subscription billing (Stripe), role-based auth, multi-tenant data models, admin dashboards - Real-Time Features: WebSocket-powered dashboards, live notifications, chat, activity feeds - AI Integration: chatbots, document Q&A (RAG), workflow automation built on the OpenAI API - Backend & APIs: REST and GraphQL services on Node.js/NestJS, clean database design (PostgreSQL, MongoDB), caching with Redis Core stack: React, Next.js, TypeScript, Node.js, NestJS, Express.js, MongoDB, PostgreSQL, Redis, REST, GraphQL, WebSockets, JWT/OAuth, Stripe, Docker. AI-assisted workflows are part of how this gets built: [Cursor/Copilot] for scaffolding, [Claude Code/ Codex] for architecture review, so more of the timeline goes toward the parts that actually need a human: data modeling, security, testing. Before joining Upwork, freelance clients hired me directly to build systems like this, not tutorials, not toy projects. If you need an MVP ready for real users, a SaaS feature shipped without breaking what's already live, or an AI feature added the right way, send over the brief. Expect a reply within 2 hours, with real questions and a rough scope, not a copy-pasted intro.
