Sheikh Tanvir Ahmed

I’m serving as a Lecturer at the Dept. of CSE, United International University, and a Computer Science and Engineering graduate of the same university. Previously I was a Software Developer at Popular Travel IT, working on distributed systems, microservices, cloud infrastructure, and observability. Before that, I worked as an Intern Engineer in the MedisonAI team at Samsung R&D Institute Bangladesh.

My research looks at how machines learn structure in what they see. Outside of work I enjoy competitive programming.

Research interests

Computer vision & structured representations
