About
I spent nearly a decade building mobile SDKs and products at Microsoft, Branch Metrics, and AppNexus before going through Y Combinator.
Now I run Pomona App Studio, where I design, build, and ship iOS apps end-to-end — from concept through App Store launch. Every app is built with SwiftUI, backed by real infrastructure, and maintained with the rigor I learned in big tech.
