Worked on the JetBrains/skiko repository to optimize OpenGL rendering performance on Linux by replacing glFinish() with glFlush() in the redrawer. This change enabled better CPU-GPU overlap, reducing stalls and resulting in higher frame rates and smoother rendering, as confirmed by performance tests. The approach focused on minimizing idle times, which may also contribute to improved power efficiency for Skiko-based applications. Demonstrated expertise in graphics programming, OpenGL, and performance profiling, with the solution implemented in C++ and Kotlin. The work included thorough documentation of the rationale and impact, along with clear Git-based change management and code review practices.
