Worked on the meshtastic/firmware repository to address threading and communication issues in embedded systems using C++ and multithreading techniques. Focused on stabilizing native builds by implementing a binary semaphore with pthread synchronization primitives, replacing stub methods that previously caused unreliable telemetry and mesh communication. This solution enabled reliable bidirectional LoRa and telemetry over the mesh, as well as MQTT gateway operation on native platforms. The work included cross-platform improvements, build hygiene updates, and integration with ARCH_PORTDUINO, ensuring portability and correct compilation. Validation was performed on ARM64 hardware with LoRa radio, demonstrating attention to robust, hardware-validated embedded development practices.
