Expo Developer
Senior Mobile Engineer — Production Expo apps, EAS Build, App Store delivery
I am a Senior Expo Developer based in London with hands-on production experience across greenfield and brownfield Expo projects. I have built, tested, and shipped to both the App Store and Google Play — owning the full lifecycle from architecture to release.
At Stadion Ltd, I built a standalone retail mobile app from the ground up using Expo and the Bare Workflow. I set up EAS Build for CI/CD pipelines, configured OTA update channels for staged rollouts, and handled App Store / Play Store submission, review, and release management — all as the sole frontend engineer on the project.
At Energize Me UK, I worked on a greenfield Expo app integrating Apple Watch via HealthKit, conversational AI features, and real-time health data tracking. The project demanded careful attention to native module bridging and platform-specific behaviour while keeping a single cross-platform codebase.
