What I'm looking for

I'm seeking Senior, Staff, or Principal mobile roles in fintech, payments, or high-integrity mobile products, where I can own end-to-end delivery, shape architecture, and mentor engineers.

I've built iOS, tvOS, and React Native products at Nagra Media UK for global streaming platforms including FIH, IBU, Eurovision Sports, and Claro tv+, used by millions. I deliver production streaming with AVPlayer, Bitmovin, HLS, FairPlay/Widevine DRM, AirPlay, Server-Driven UI, and reliable CI/CD.

I've also owned Solana wallet and gasless trading flows at Token.com, improved its React Native video feed performance 2×, and shipped regulated banking features for DBS Digibank. Across mobile banking, OTT, IoT, health AI, and independent products, I lead architecture, mentor engineers, and take products from concept through App Store release.
