Profile

A practical approach to building useful software.

Software engineer working across applications, software products, real-time systems, and intelligent software projects.

I work across software products, applications, and intelligent systems. My experience includes product development, mobile applications, real-time features, and technical work shaped by practical engineering needs.

Alongside product development, I have also worked on AI and research-oriented projects, including facial analysis, health-related sensing, and technical experimentation connected to real software systems.

My academic and professional journey has taken me across Bangladesh, China, and international collaborations. That experience has shaped how I approach engineering work: stay clear, stay practical, and let the quality of the implementation speak for itself.

Beyond work

Beyond work

A few interests that keep me grounded outside software.

Cricket

Cricket has been an important part of my life for many years. I play as an all-rounder with right-hand batting and bowling, and the game has shaped my discipline, teamwork, and competitive mindset.

Quiet interests

I also enjoy small quiet moments in nature and have a soft spot for animals, especially cats, dogs, and swans.
