In August 2025, Mzb contributed to the tailscale/tailscale repository by developing two features focused on backend development and networking. They introduced a new Makefile target to automate code generation, streamlining the developer workflow and reducing manual intervention. Additionally, Mzb enhanced DNS configuration by implementing UseWithExitNode support, allowing specific DNS resolvers to be used during exit-node sessions and refactoring the system to handle split DNS routes more reliably. Working primarily with Go and Makefile, Mzb’s changes improved flexibility and reliability for both developers and end users, demonstrating a thoughtful approach to build automation and network configuration challenges.
