1. About

I’m a Computer Science and Engineering graduate of United International University (UIU) with a 3.99/4.00 CGPA, summa cum laude. I currently work as a Software Engineer at Popular Travel IT, part of the Italy-based Popular Travel Group.

My work spans distributed systems, microservices, cloud infrastructure, DevOps, observability, backend development, and AI-driven software systems. Before that I was an AI & Software Engineering Intern at Samsung R&D Institute Bangladesh, and as a teaching assistant I mentored students and counseled those on academic probation.

My research looks at how machines learn structure in what they see. Outside of work I enjoy competitive programming and have solved hundreds of problems across major online judges.
