Over five months, John contributed to the john0312/hitcon-pcb-badge repository, developing and refining embedded firmware and hardware features for a multi-version STM32-based badge. He integrated accelerometer-driven UI updates, implemented robust IMU and USB/HID services, and resolved hardware signal routing conflicts to improve reliability. John applied C, C++, and Python scripting to build modular device drivers, enhance I2C communication, and support real-time operating systems. His work included refactoring for maintainability, expanding hardware abstraction, and strengthening error handling. By addressing both architectural and low-level issues, John delivered a maintainable, testable codebase that improved system stability, user experience, and release readiness.
