What I'm looking for

I seek a hands-on role where I can own end-to-end development—backend, frontend, or mobile—at a team valuing autonomy, scalable systems, and continuous delivery.

I am a Full-Stack Developer with 3+ years building end-to-end products, including a production IPTV streaming platform where I owned architecture, UI/UX, and technical decisions. I have delivered mobile, TV, web, and backend systems, and built large-scale data automation pipelines processing millions of records.

My work spans React Native, Next.js, Node.js, Python (Flask/FastAPI), and databases like PostgreSQL and MongoDB; I optimize performance, deploy CI/CD pipelines, and fix deep dependency issues in production. I seek backend, frontend, mobile, or fullstack roles where I can take ownership and solve complex technical challenges.
