Senior Full Stack Developer

About me

Full-stack web developer with a solid background in modern JavaScript ecosystems. Proficient in building dynamic, responsive interfaces using React, Next.js, and TailwindCSS, combining design precision with intuitive user experience.

On the backend, I build scalable APIs using Node.js, NestJS, PostgreSQL, and MongoDB, deploying and containerizing services on AWS with Docker.

I use AI coding agents (Claude Code, Codex) daily as accelerators, and integrate the Anthropic and OpenAI APIs into product features — from automation pipelines to real-time assistants — without sacrificing code quality.
