🏆 Top Rated Plus | Top 3% on Upwork | 100% Job Success | 5+ years building production systems
I'm a Fullstack Developer who ships production systems, not prototypes. My largest engagement was a 1,056-hour Next.js build for industrial manufacturers - multi-tenant architecture, Clerk Auth, PostgreSQL, Stripe billing, role-based access control across organizational hierarchies. The client kept me for 10 months. Before that, I spent 885 hours as a React Node.js Developer building a real-time mentorship platform from zero - Socketio, WCAG compliance, complex RBAC, production deployment serving active users daily.
I take single-developer ownership of the fullstack. Database schema, backend API, frontend UI, deployment pipeline - one person, one codebase, no handoff friction. 80% of my Upwork work has been this model: a founder or product team hands me a problem and I deliver a working system. I write TypeScript everywhere, I ship on Vercel or GCP, and I build things that don't need to be rewritten six months later. I've solved 650+ problems on LeetCode and competed in algorithmic programming at A2SV - I don't just use frameworks, I understand what's underneath them.
My stack centers on Next.js, React, Node.js, TypeScript, and PostgreSQL. On the backend I also work with Python, FastAPI, Django, Express, NestJS, MongoDB, Supabase, and Firebase. I build cross-platform mobile apps with React Native when the product needs one. Stripe, Clerk, JWT, OAuth for payments and auth. Vercel, GCP, AWS, Docker for infrastructure.
I'm a strong fit if you need a senior Fullstack Developer to own your product end-to-end - SaaS platforms, internal tools, MVPs that need real architecture, or existing codebases that need an engineer who can read what's there and extend it without breaking things.

I'm a senior full-stack web developer with 6+ years and over 17,000 hours spent building, testing, and shipping production web applications from end to end. I work primarily across React and Next.js on the frontend and Node.js — with both Express and NestJS — on the backend, backed by PostgreSQL and MongoDB, with TypeScript throughout.
My standard isn't something you have to take on faith. I'm in the top 2% of all contributors on Stack Overflow, with more than 9,800 reputation earned by helping developers around the world solve real engineering problems. That number isn't self-awarded — it's the verdict of thousands of developers who found my answers clear, correct, and worth upvoting. I bring that same precision to every line of code I write for a client.
When I take on a project, I build the full slice. On the backend, I work with Express for lean, focused services and NestJS when a project needs the structure of a modular, dependency-injected architecture that stays organized and testable as it grows.
I model data in whichever database fits the problem — PostgreSQL for relational integrity, with migrations, transactions, and proper indexing, or MongoDB for flexible, document-driven workloads — and I access it through a type-safe ORM. I expose clean, validated endpoints with typed DTOs, and I reach for caching and background jobs when a feature needs to scale. On the frontend, I build polished, accessible interfaces in React and Next.js.
I write in TypeScript end to end so bugs surface at compile time instead of in production, and I cover the logic that matters with unit and integration tests so that refactors stay safe and releases stay calm.
I ship through CI/CD pipelines with Docker, so what runs on my machine is exactly what runs in yours — and I use modern AI-assisted tooling such as Cursor and Claude Code to move quickly without compromising any of it.
Whether you need someone to untangle an existing codebase or build something new from an empty repository, I take full ownership of the result: I communicate clearly, I meet my deadlines, and I deliver work you don't have to babysit. Recently, I've built a hospital appointment-scheduling calendar, a volunteer-teacher registration and follow-up system, and several full MERN web applications.
Send me a message describing what you're building, and I'll tell you honestly how I'd approach it.
