01. About Me

I'm a Software Engineer with deep roots in mobile development and a track record of managing high-performing engineering teams. I've built and shipped products used by tens of millions of people, and led engineering efforts at companies ranging from early-stage startups to large-scale consumer platforms.

At Google, my teams are responsible for delivering features for Google Search and its related properties — spanning mobile app development, visual media creation web services, and user engagement features driven by AI.

I'm always looking for opportunities to have impact, learn, and collaborate with ambitious peers.
