Rockstar🎓
Top SchoolPirun Lee is a software engineer with 6 years of focused experience in embedded systems and IoT, currently contributing to Nordic Semiconductor's nRF Connect SDK. He has a deep background in firmware, BSP integration, and automotive ECU development from a decade-plus tenure at Quanta, where he worked on Linux kernel drivers, HAL ports, and a wide range of sensor and communication interfaces. At Nordic he notably improved the serial LTE modem (SLM) app—adding GPIO AT commands, UART hardware flow control, flash-backed settings, Zephyr HTTP client adaptations, DFU enhancements, and Thingy:91 support. Comfortable across BLE, cellular, Wi‑Fi, and low-power designs, he blends hands-on driver work with system-level orchestration for production devices. Based in Taoyuan City, Taiwan, he pairs pragmatic engineering with a principled outlook—his GitHub motto reads "Let justice be done though the heavens fall"—hinting at a meticulous, quality-driven approach.

Contributions summary:Pirun significantly contributed to the serial LTE modem (SLM) application within the nRF Connect SDK. Their work involved the implementation of GPIO AT commands, including configuration, reading, writing, and toggling of GPIO pins. Furthermore, they improved UART AT command functionality by adding features for hardware flow control and flash memory storage of settings. They also adapted the application to newer Zephyr HTTP client APIs and added overlay files and configurations for the Thingy:91 target platform, along with DFU support improvements.
