TanzimHello, world.
Dhaka, Bangladesh / Remote Worldwide

Engineer by training.
Designer by conviction.

I am a Fullstack Architect who believes exceptional software is born where deep engineering rigor meets refined visual taste. Over 6+ years of building distributed web applications, high-throughput microservices, and bespoke interactive platforms, I bridge the gap between creative art direction and robust cloud systems. Off the keyboard, I tour remote mountain ranges and hone reflexes in competitive esports.
