Highlights

Architected and shipped Salus / Dert AI end-to-end in React Native — RevenueCat payments, Meta Conversions API attribution, and the full Firebase stack.

Cut Chordie AI cold start from 9s to 4s (55% faster perceived startup) by lazy-loading Firebase and deferring analytics SDK init.

Built and owned RevenueCat subscription & one-time purchase flows, feeding server-side Conversions API for accurate ROAS.

Maintained Guitar Effects natively in Kotlin and Swift; Chordie pairs a Unity (C#) core with a React Native shell and native bridges.

Built the release pipeline from scratch: Fastlane + GitHub Actions CI/CD, automated store submissions and TestFlight distribution.

Automated a server-side event pipeline with Node.js + AWS SES for lifecycle emails and conversions.

Scrum Master for a cross-functional team; mentored 10+ interns and junior developers.
