Who I am
A bit about me

I'm a Python / Django Backend Engineer who graduated from Dhaka International University with a B.Sc. in Computer Science & Engineering. I joined my first company as an intern and grew into a Junior Software Engineer — shipping 5 production systems that real businesses run on today.

Beyond code, I'm driven by solving hard problems. My thesis on Jute Disease Prediction using deep learning achieved 95.7% accuracy — and was recognised as a meaningful contribution to Bangladesh's agricultural sector.

When I'm not building backends, I'm participating in hackathons, reading about distributed systems, or exploring new ways AI can solve real-world problems.

🌱
Always Learning
Hackathons, research, and continuous skill-building are my baseline.
