Mobile engineering
Mobile work keeps pulling me past the screen: a native bridge for biometrics, a wallet session inside a messenger, a realtime audio pipeline. I build those layers along with the app.
Multimodal AI on mobile
LegalAgent's mobile client had to handle voice and chat in two languages. I shipped it in Expo around OpenAI's Realtime API for voice and the Vercel AI SDK for chat, with bilingual transcription and synthesis in Spanish and English.
Regulated mobile banking
Wink was banking without a branch visit, so identity checks couldn't depend on one either. I built biometric authentication through a React Native native bridge, which let KYC and login happen on the phone.
Blockchain messaging and retail AR
Sense.chat is a secure chat app built around data privacy, and it needed an EOS wallet inside the messenger. I optimized the React Native app and integrated mainnet wallet and transaction flows.
Tractor Supply already had a retail app and wanted product previews, so as a consultant I built the ViroAR feature for them.
