PROFILE
Jack Kim
Worked on the psleng/nexus-build repository to deliver hardware-focused build automation, firmware update workflows, and device control systems for embedded Linux platforms. Developed features such as J7200 and Perle IOLAN board support, end-to-end Device Firmware Update processes, and a GPIO control system with RTC initialization and LED status monitoring. Leveraged Python scripting, Makefile automation, and shell scripting to streamline build processes, enable reliable in-field upgrades, and improve hardware integration. Enhanced documentation and onboarding by clarifying flashing procedures and configuration steps, resulting in more maintainable deployments and reduced setup ambiguity for both developers and operations teams across multiple hardware targets.

2 Commits • 1 Features
May 1, 2026In May 2026, delivered a GPIO Control System with RTC initialization and LED status monitoring for the Nexus build (psleng/nexus-build). Implemented Python tooling to drive GPIOs, configure and monitor status LEDs, and validate RTC boot readiness. Refactored console configuration by removing ttyS3 to reduce boot-time risk and simplify hardware integration. Added an RTC check script to ensure reliable RTC chip enablement, improving device startup stability and status visibility for operations and support teams.
