Worked on SuperTux and mpv-player/mpv, focusing on performance, reliability, and user experience. In SuperTux, refactored the main loop to use nanosecond-precision timing and capped time steps, resulting in smoother gameplay and consistent frame pacing. Improved camera rendering by synchronizing screen size updates, eliminating visual glitches during window resizing and scaling. For mpv, enhanced Wayland session compatibility by updating environment variable detection logic to support WAYLAND_SOCKET, reducing startup issues across diverse compositors. Demonstrated strong skills in C++, system programming, and performance optimization, delivering targeted, maintainable changes that improved cross-platform stability and gameplay accuracy in both C++ and Lua environments.

November 2024 monthly summary for mpv: Delivered a Wayland detection enhancement to improve compatibility with Wayland compositors that expose sockets via WAYLAND_SOCKET. The change strengthens the detection logic by considering WAYLAND_SOCKET in addition to WAYLAND_DISPLAY, affecting console.lua and wayland_common.c. This work reduces user friction and increases reliability of Wayland session startup across diverse environments (commit: 46574d479d8f91ca03c6593ef6a3073407fb408d).
