I help teams build, stabilize, and extend mobile products using React Native or native Android with Kotlin and Jetpack Compose. Bring me in when an app needs senior technical ownership, an inherited codebase needs attention, or a difficult integration is holding up delivery. How I can help • React Native development: implement cross-platform features and work through platform-specific behavior. • Native Android engineering: build Kotlin features and improve application structure, device behavior, and maintainability. • Codebase recovery: investigate failures, explain root causes, and implement agreed stabilization work. • Integrations and data: connect APIs, authentication, Firebase, local storage, notifications, and Bluetooth or other SDKs as needed. • Release and handoff: test critical flows, address performance concerns, support store submission, and document the work. My experience includes native Android contributions to 1OR Health and cross-platform mobile delivery. I can help evaluate whether React Native or a native approach fits your requirements. Start with a focused mobile review or a scoped implementation. Consulting is $100/hour, with scope and estimated effort agreed before work begins.
