01 // About

Engineering solutions that bridge the gap between complex infrastructure and user experience.

Hey! I'm a Computer Science undergraduate at AIUB. I specialize in backend systems, scalable web applications, automation, and self-hosted infrastructure.

Recently, I've architected The Perfume Shop (turnkey luxury e-commerce with 3D WebGL flacons & bKash/SSLCommerz payments) and KaajBondhu (a local service marketplace). I love transforming ideas into high-performance, real-world systems.
