Worked on stabilizing and maintaining backend systems across two repositories, focusing on build reliability and rendering stability. In fosskers/raylib-1, addressed dependency drift by synchronizing external library versions in build.zig.zon, which improved CI consistency and reproducibility using Zig and build system management techniques. For david-vanderson/dvui, delivered targeted bug fixes in the SDL Android backend, clarifying error messages and reverting problematic changes to restore OpenGL context handling. This approach reduced debugging time and improved user experience by ensuring stable rendering paths. All work emphasized traceable commits and careful maintenance, demonstrating depth in backend development and cross-platform build management.
