Recently, I led the development of HealthFlexx AI, a healthcare & fitness platform with 20K+ installs including its mobile app, backend and connected device integrations. I work directly with hardware manufacturers in China and customers in the US, handling BLE connectivity, data communication, troubleshooting, testing and production support. My strongest expertise is at the intersection of Flutter, AI, IoT/BLE, hardware integrations and cloud backends. What I Build • Flutter iOS & Android apps • React Native applications • AI-powered apps & OpenAI/ChatGPT integrations • IoT, Bluetooth/BLE & hardware integrations • Healthcare & fitness platforms • Node.js/TypeScript backends • REST & GraphQL APIs • Firebase, Supabase & cloud applications • Real-time apps and dashboards • App Store & Google Play deployment Core Stack • Mobile: Flutter, Dart, React Native, Android, iOS • Backend: Node.js, TypeScript, Firebase, Supabase • Database: PostgreSQL, MySQL, MongoDB • Cloud: AWS, Google Cloud • AI: OpenAI, ChatGPT, Generative AI • Devices: Bluetooth, BLE, IoT • Native: Java, Kotlin, Swift I also use AI-assisted workflows with Claude and Cursor to accelerate development while maintaining strong architecture, testing, code quality, and maintainability. From product architecture to development, hardware integration, testing, deployment and post launch support, I can handle the complete product without requiring multiple developers. If you are building a mobile app, AI product or IoT/BLE solution, send me your requirements and I’ll help define the right technical approach.
