Ruminations of a data scientist turned engineer - on LLMs, deep learning, and building AI systems.

I'm a data scientist, on sabbatical. I recently built clarifyit.ai

Previously, I led an AI and data engineering team at Eka.care. Training LLMs, building retrieval systems, managing vLLM deployments, and owning the product roadmap for our AI tools in healthcare. Before that, I worked on search ranking and data pipelines at Udaan, and was a visiting researcher at the National Center for Biological Sciences (NCBS).

I write here about what I learn along the way.
