About me

I'm a final-year CS student at BRAC University who splits time between shipping production software and chasing research. By day I build React/Next.js products as a frontend developer at FourbTech; alongside that I work as an ML research assistant on biomedical AI, and do computer vision for BRACU DUBURI, Bangladesh's first autonomous underwater vehicle team.

Most of what I build sits at that intersection: full-stack products, computer vision and language models applied to real problems, and a research thread that doesn't let go — my thesis, ExplainFake, fuses audio-visual deepfake detection with explainability built directly into the architecture.
