Data Engineer turning raw data into AI products.

I'm Saurav — I build retrieval pipelines, multi-agent systems, and the data foundations that make machine learning actually ship.

About

I'm obsessed with the messy, beautiful work of making AI useful.

Data Science is my favorite topic. I love sitting at the seam between pipelines and models — moving data from somewhere ugly into something a model can reason over. Lately I've been building RAG systems, multi-agent harnesses, and trading bots powered by LLMs.
