Worked on the facebook/igl repository to address image clarity issues in OpenGLView for high-DPI and Retina displays. Focused on a targeted bug fix by updating the rendering logic to use the device’s screen scale rather than contentsScale, resulting in sharper image output and improved user experience. The solution maintained full API compatibility, isolating changes to the rendering path without affecting consumer-facing interfaces. Demonstrated proficiency in OpenGL, Objective-C, and iOS development while resolving a specific visual fidelity problem. The work contributed to reduced blur-related support tickets and aligned with product quality goals through careful code review and iterative improvement.
