Hello

I'm Rajdeep

I build AI agents that cut operational costs in half. Currently compressing drug discovery from years to quarters.

I lead GenAI at a biomedical data company, building AI systems for top-10 pharma. I write about what actually works: agents, production systems, and clear thinking.
