Hi, I'm Sanjay. I lead, build, and ship.
I build full-stack products and work on several MSN apps at Microsoft AI. I also maintain open-source tools and advise an early-stage AI analytics startup.

About
I build products across the stack
I build full-stack products and work on the front-end of several MSN apps at Microsoft AI. My work covers user-facing pages, shared libraries, and architecture for those apps.
My projects span web, mobile, and desktop apps, backend services, data stores, and connected devices. I also work on performance, data accuracy, testing, automation, and live-site quality, using Azure DevOps, Loop, and CI/CD pipelines across teams.
Outside Microsoft AI, I advise an early-stage AI analytics startup as a fractional CTO, covering product architecture, backend and front-end development, AI and agentic AI systems, and infrastructure. I've built open-source tools and side projects since 2015. My current focus is Tooloogle, a platform of formatters, converters, generators, and developer utilities.
