About Me
Hi there, I'm a Machine Learning Engineer / Data Scientist with close to 6 years of experience in recommendation systems, search, and applied GenAI. I'm currently Founding Data Scientist (AI/ML) at Shuru, building hyperlocal personalization and multilingual search for a 20M+ user base, along with multi-agent LLM systems and a computer vision pipeline for content safety.
Before this, I worked on credit risk and fair-lending models at Scienaptic AI, scaled Zomato's home page recommendation engine, and built recommendation and ranking systems as a Machine Learning Engineer at Hotstar. I studied Mathematics and Computing at IIT Guwahati.
On this site, I write about ML and AI — concepts, systems, and projects built from scratch rather than through framework abstractions. Check out my writings for the series.
