Hi, I'm Sanjay. I lead, build, and ship.
I lead frontend at Microsoft and build full-stack products end-to-end — from architecture and shared libraries to the small tools that ship on the side.

About
A bit about me
I'm a UX/UI developer focused on sports web experiences. I currently lead frontend for Microsoft's Bing & MSN Sports, where I own shared infrastructure and most of the user-facing pages — the libraries, architecture, and patterns the team builds on.
Day to day that means driving performance and data accuracy through testing, automation, and live-site quality tracking, and collaborating across teams with the usual Microsoft stack — Azure DevOps, Loop, and CI/CD pipelines.
Outside Microsoft, I advise an early-stage AI analytics startup as a fractional CTO, and I've been building open-source tools and side projects since 2015 — currently focused on Tooloogle, a growing platform of developer utilities.
