PROFILE
Nicolo Micheletti
Michele Lettini developed core features and infrastructure for the Mentra-Community/MentraOS repository, focusing on cross-platform mobile systems for smart glasses and real-time media workflows. Over 15 months, Michele engineered multilingual audio streaming, OTA update flows, and gallery synchronization, integrating technologies like React Native, TypeScript, and Bluetooth LE. The work included deep refactoring for reliability, secure device onboarding, and extensible API and SDK layers, addressing both Android and iOS. By implementing robust event-driven architectures and optimizing audio, camera, and notification pipelines, Michele improved system stability, user experience, and developer velocity, demonstrating strong backend, embedded, and UI engineering depth across the stack.

Jan 1, 2026January 2026 monthly summary for MentraOS focusing on delivering security-critical fixes, UX polish, and robust media/workflow enhancements that directly improve user productivity and reliability of media capture and sync pipelines. Key achievements delivered this month include: - Hotfix: disable RGB LED control authority commands in MentraLive to prevent unauthorized control flows, reducing security risk and potential misuse. - GalleryScreen UI enhancements: loading placeholders with fade-in, background color alignment with shimmer placeholders, layout refinements, and validation for downloaded photos to improve perceived performance and data integrity. - GallerySyncService improvements: added GalleryModeSync to manage gallery mode state, implemented immediate camera roll saving, and introduced post-sync query handling for data consistency. - Electronic Image Stabilization (EIS) integration: enabled EIS across CameraNeo and RtmpStreamingService and cleaned up legacy EIS code, improving video stabilization across devices. - MediaCapture LED brightness and flash duration improvements: added adjustable LED brightness with clearer logging during recording, and shortened photo flash LED duration to 1 second for better UX and performance. Overall impact and accomplishments: These changes collectively strengthen security, reliability, and performance of core media workflows, reduce manual troubleshooting, and provide a smoother user experience during gallery capture, viewing, and synchronization. OTA/firmware metadata updates also support safer rollouts and device compatibility checks. Technologies/skills demonstrated: Android-like mobile development patterns (Kotlin/Java), UI/UX polish, background services, logging and observability, WebSocket integration patterns, EIS integration, and proactive code maintenance (refactors and cleanup).
