What I'm looking for

I'm looking to build and ship ambitious mobile products where I can own architecture, performance, offline experiences, release systems, and product outcomes while mentoring engineers.

At Deplike, I built and shipped Chordie AI from zero to production for 2M+ users, owning its React Native architecture, Firebase stack, native Swift and Kotlin audio bridges, payments, experimentation, and release pipeline. I cut cold start from 9s to 4s and built scalable, 60fps song browsing and real-time playback experiences.

I've shipped six iOS and Android apps, including fully offline local-first products such as Penno and Conjugaizen. I also lead Scrum ceremonies, mentor 10+ developers, and build reliable CI/CD workflows with Fastlane, GitHub Actions, and OTA updates.
