Rockstar🎓
Top SchoolAndrew Kaster is a C++ systems engineer with 11 years of experience building and refining low-level software for operating systems, embedded flight systems, and a web browser. Based in Denver, he combines production-grade embedded work at Lockheed Martin with open-source stewardship as a maintainer of Ladybird Browser and key contributions to SerenityOS and the Jakt language. He specializes in compiler, build-system and runtime improvements, testing and CI automation, and has a track record of refactoring core OS components to improve stability and prevent deadlocks. Comfortable across VxWorks, Yocto Linux, and Windows compatibility stubs, he brings disciplined engineering practices from DO-178B and large defense projects to FOSS development. A practical problem-solver, he often pairs feature work with infrastructure—adding build systems, linting, and commit-validation workflows to make projects more maintainable.
