Most projects don’t fail at the idea stage — they fail during execution (bad architecture, unstable APIs, rushed integrations). That’s where I come in.
I’m a Full Stack Engineer (React, Node.js, NestJS, PostgreSQL) focused on building production-ready systems — not quick fixes. I’ve worked on SaaS platforms, AI chatbots, and automation tools where performance, scalability, and real-world usage actually matter.
I don’t just “build features” — I make sure your product works reliably when real users hit it.

Frontend:
- React
- Next.js
