I’m a backend-focused full-stack developer with expertise in API design, automation, and browser extension development. I’ve built scalable scraping systems, secure APIs, and serverless solutions using Python, FastAPI, Nodejs, and Vercel. One of my key projects includes developing a Firefox extension with a serverless Nodejs backend on Vercel, integrated with Supabase and secure OAuth2/JWT authentication. My work emphasizes performance, scalability, and clean architecture.
