What I'm looking for

I'm open to globally remote roles and can work EST-aligned hours, from 9 AM to 6 PM US Eastern.

At Sterling Bank, I lead mobile architecture for banking apps serving 100K+ users. I designed and built a hardware-backed device-binding system in Kotlin and Swift, with non-exportable keys and on-device transaction signing.

I’ve shipped banking features including transfers, payments, investments, and KYC onboarding, where onboarding completion reached ~90%. I also improved crash-free sessions to ~99% and added TalkBack and VoiceOver support across key flows.

Before Sterling Bank, I built mobile products at Remedial Health and ScholarX Inc., including an offline-first pharmacy operations app and an edtech app with video learning. I also bring backend experience with Node.js and PostgreSQL, and built Otay, an AI-powered document RAG platform integrated with a React Native app.
