Worked on OpenWrt and Linux kernel repositories, delivering features and fixes for embedded systems and network devices. Addressed a regression in OpenWrt’s ramips/mt7621 target by disabling Energy Efficient Ethernet in the device tree, restoring stable connectivity. Refactored RTC timekeeping on MIPS platforms in geerlingguy/linux, removing dead code and unifying time retrieval through the RTC library. Improved OpenWrt package reliability by aligning bind-libs versions to prevent runtime errors. Added vendor web interface flash support for ASUS RT-AX53U, streamlining firmware installation. Demonstrated expertise in C, Makefile, device drivers, and package management, with a focus on maintainability and user experience.
March 2026 – DragonBluep/openwrt: Delivered Vendor Web Interface Flash Support for ASUS RT-AX53U. Implemented a new build flow to generate an initramfs-factory.trx image that can be flashed via the vendor's WebGUI, followed by a standard upgrade using sysupgrade-squashfs.bin. Included vendor compatibility checks and clear user instructions. Documented kernel size constraints (TRX v2) and added conditional logic to the Build/asus-trx macro to avoid hard failures if input exceeds expectations. This work reduces user friction, accelerates adoption of OpenWrt on ASUS RT-AX53U, and lowers support overhead by enabling a streamlined, one-step flashing path.
