At Reenbit, I own mobile development for Actuvi, My Rehab Pro and Thrive365, taking the work from requirements and architecture through releases and production support. I designed a white-label architecture that lets three iOS and Android apps share one React Native codebase.

For these healthcare products, I integrated more than 10 Bluetooth Low Energy medical devices and delivered HealthKit, Health Connect and Dexcom CGM integrations. I also implemented CI/CD and over-the-air updates, and built real-time chat, media sharing and audio/video calling.

I independently built and launched Primey, an AI-powered app, covering product design, mobile and backend architecture, implementation and its App Store launch. It reached 1,000 daily active users through organic acquisition without paid advertising, and I continue to own its development and production support.
