I build the parts of a product that aren't allowed to go down APIs under real traffic, computer vision pipelines that run unattended at scale, and the real-time infrastructure underneath. Based in Hyderabad, working with teams everywhere.

About

I started as a frontend intern shipping UI tickets. Three years later I was the contract CTO of a healthcare startup, owning the technology roadmap, and the engineer who put a computer vision model into a pipeline making 40,000+ automated decisions a day with no human in the loop. In between, I've built real-time systems with Socket.io, designed REST APIs and MongoDB schemas for production load, and trained a segmentation model over 6,000,000 iterations until it held at 99%+ accuracy. I work across the stack because production systems don't respect the boundary between frontend, backend, and ML somebody has to own the whole path from request to result.
