About Me

Engineer by day, indie app builder by night.

I'm a Staff Software Engineer at Google on the Firestore team, where I work on building and scaling one of the world's most widely used NoSQL databases. I love systems that are fast, reliable, and elegant under the hood.

Outside of work, I channel that same energy into crafting iOS apps — combining AI, thoughtful UX, and real-world utility. My projects range from an AI wardrobe stylist to a group travel companion app.
