Developed and maintained the hitcon-pcb-badge repository over five months, delivering 29 features and resolving 14 bugs across embedded hardware and firmware. Focused on robust sensor integration, USB/HID enhancements, and multi-version hardware support, the work included accelerometer-driven UI updates, IMU service development, and proximity data reporting. Applied C, C++, and Python to implement device drivers, I2C communication, and real-time operating system features, while refactoring USB logic for modularity and maintainability. Addressed hardware conflicts through PCB design changes and improved system reliability with error handling and timeout mechanisms, resulting in a stable, configurable platform ready for future feature expansion and releases.
