I build production AI systems and dig into how they work underneath the abstractions.
About
I'm a Senior AI Engineer based in Ahmedabad, India. I started out in classic machine learning, building loan-risk models, and moved into LLM systems once they became real enough to ship.
For the past year I've been building the AI layer of Mitoo, a multi-tenant business platform, on my own: an assistant that does real work across six apps, an AI agent that phones sales leads, and an AI voice interviewer. Most of that work isn't the model. It's making something probabilistic behave inside software that has permissions, tenants, money and real users.
I like going down the stack: understanding what happens underneath the APIs, not just calling them.
