Jul 1, 2025July 2025: Delivered two major features (Isochronous Channels (ISO) support in the bench app and Apple Media Service (AMS) profile with GATT server/client roles and async playback controls) and two critical reliability fixes (standardized logging with a colored formatter via environment-driven config, and robust connection handling with a standardized disconnection flow and peripheral handle lookup). These changes enhance testing fidelity for ISO/AMS workflows, improve stability across BLE connections, and reduce debugging time through consistent logging and configuration. Demonstrated skills in Bluetooth LE, async programming, code refactoring, and maintainability improvements across the google/bumble repository.
