During June 2026, contributed a UI performance optimization feature to the koala73/worldmonitor repository, focusing on enhancing badge pulse animations. The work involved refactoring existing CSS animations to utilize transform and opacity properties, enabling GPU acceleration and reducing reliance on resource-intensive box-shadow effects. By introducing new pseudo-element structures, the visual consistency of the badges was maintained throughout the animation cycle. This approach resulted in smoother frame rates and decreased CPU and GPU load during animations, directly improving perceived frontend performance. The solution established a reusable pattern for future animation work, demonstrating proficiency in CSS, frontend development, and performance optimization techniques.
