Worked on the snowplow/snowplow-javascript-tracker repository to enhance the stability and reliability of resize event handling in web applications. Addressed a bug in ResizeObserver by implementing a debounced approach using requestAnimationFrame, which prevents undelivered notifications and reduces the risk of infinite loops caused by synchronous layout reads. This solution ensures that browser properties are read asynchronously, resulting in more consistent behavior across different browsers and minimizing UI jitter during resize scenarios. The work was carried out using TypeScript and JavaScript, leveraging Browser API expertise to improve front-end reliability and deliver a smoother user experience during dynamic layout changes.
