Over seven months, Nami Ltd contributed kernel, driver, and build system improvements to the coolsnowwolf/immortalwrt and openwrt/packages repositories, focusing on stability, maintainability, and hardware compatibility. Nami upgraded Linux kernel versions, refactored device driver headers, and streamlined network interface setup using C, Makefile, and shell scripting. Their work included patch management to align with upstream changes, memory management fixes to prevent resource leaks, and enhancements to build system configuration for more reliable packaging. By addressing low-level hardware detection and dependency alignment, Nami reduced build failures and runtime errors, demonstrating depth in embedded systems, kernel development, and version control practices.
