About Me

A quick look at my background, what I build, and how I work.

Who am I?

I'm a full-stack engineer from Dhaka, Bangladesh, with a BSc in Computer Science & Engineering from the University of Asia Pacific. I ship production systems across SaaS, HRMS, and EdTech — from tenant-isolated backends to user-facing dashboards.

What do I specialize in?

SaaS MVP delivery end-to-end — multi-tenant architecture, Django/FastAPI and Node.js/Express APIs, dynamic RBAC, e-commerce SaaS, LMS platforms, and RAG-powered AI integrations.

What have I built?

ChampKoder — an interview prep LMS with 200+ daily users, Judge0 code judging, and gamification. StoreSetup — a multi-tenant e-commerce SaaS with custom domains and POS. WeekWins — a weekly goal and productivity platform. Smart Hiring — recruitment SaaS with dynamic RBAC.

Why hire me?

You get someone who owns features end-to-end: API design, database modeling, frontend integration, Docker deployment, CI/CD on AWS, and clear communication on remote timelines.
