Full-stack builder with a competitive-programming habit.

I'm a final-year student at Jahangirnagar University, currently working as a Software Engineer at Skoder Technologies, where I build and maintain production FastAPI, Next.js and Laravel applications — RESTful APIs, database migrations, query optimization, and AI automation agents wired up with n8n and LLM workflows.

Outside of work I compete in contests (ICPC, IEEEXtreme, national onsites), train juniors in the IIT competitive-programming community, and ship side projects end to end — payments infrastructure, AI pipelines, computer-vision systems — usually solo, always in production shape.

Experience.
