PROFILE

Hirokazu Morikawa

Morik worked on the openwrt/packages repository, focusing on build system upgrades, dependency management, and security patching for Node.js and related components. Over six months, Morik delivered runtime upgrades, streamlined build processes, and addressed critical vulnerabilities by updating Makefiles, refining patch workflows, and validating builds across architectures. Using C, Makefile, and Shell, Morik improved package stability by simplifying build logic, upgrading ICU libraries, and ensuring reproducible builds. In DragonBluep/openwrt, Morik stabilized IPv6 tunneling by reverting disruptive kernel changes in C, restoring reliability for MAP-E and DS-Lite deployments. The work demonstrated depth in system integration and cross-platform package maintenance.
