Tanzim Hossain Romel
Software Engineer · Software Engineering Researcher
Incoming PhD student (Fall 2026) and CS graduate from BUET. I study how AI changes software development, from secure ML pipelines to developer tools. At IQVIA, I build healthcare systems that scale. I care about open source and research that makes software engineering more accessible.
Outside of work, I read a lot of history and economics, especially how civilizations rise and fall and how markets shape behavior. When I'm not debugging, I'm usually traveling or reading fiction. More about me →
