Worked on the Samsung/TizenRT repository over six months, delivering 13 features and resolving five bugs focused on embedded systems, networking, and security. Developed enhancements such as BLE multi-advertisement, power-aware flash reliability, and secure flash access control, using C, Python, and Shell scripting. Integrated Ed25519 cryptography via libsodium to strengthen OTA security, improved Wi-Fi throughput, and optimized bootloader packaging for modular upgrades. Addressed system stability through stack guard initialization, watchdog timer management, and file system concurrency fixes. Emphasized maintainability by streamlining CI/CD pipelines and refining partition management, resulting in more robust, secure, and reliable firmware for battery-powered devices.
