Matt contributed to the coolsnowwolf/immortalwrt repository by developing Hyper-V Arm64 virtualization support for the armsr target, enabling ImmortalWrt to function as a guest on Windows Hyper-V with integrated graphics, input, networking, and storage. He implemented kernel configuration changes to expand virtualization scenarios and improve cross-platform compatibility, leveraging his expertise in C and system configuration. In the openwrt/packages repository, Matt addressed a kernel-module build failure for Open vSwitch on Linux 6.12 by adding a missing dependency, stabilizing the build pipeline. His work demonstrated depth in kernel development, build systems, and dependency management, directly improving reliability and platform coverage.
