Worked on enhancing the benchmarking infrastructure for the maplibre-gl-js repository, focusing on improving the reliability and maintainability of GPU performance measurements. Developed and integrated a GPU Benchmark Synchronization feature that ensures all GPU draw calls are completed before timing benchmarks, addressing issues with inaccurate and inconsistent results. Refactored benchmark-related code out of the main source directory to streamline organization and facilitate future maintenance. Utilized TypeScript and applied expertise in GPU programming and performance optimization to implement a new synchronization method, update documentation, and revise the changelog. These changes resulted in more accurate, repeatable benchmarks and a cleaner codebase structure.
