Generative AI · LLMs · Computer Vision · Deep Learning — built with PyTorch, from first principles.

AI/ML Engineer at Benzy Infotech and M.Tech in Vision & Intelligent Systems from IIT Kharagpur (CGPA 8.36). I work across diffusion models, LLMs, and computer vision — and I like to understand things by building them, from autograd engines to vision algorithms, written from scratch rather than pulled off a shelf.

About

I'm an AI/ML engineer working across generative AI, large language models, and computer vision. My approach is hands-on and foundational: I build core machine-learning machinery — automatic differentiation, optimizers, diffusion and vision pipelines — myself, so I understand exactly how and why they work. I hold an M.Tech in Vision & Intelligent Systems from IIT Kharagpur, and alongside my work I tinker with embedded ML and run a small home GPU lab for experimentation.
