Over a two-month period, contributed to browser compatibility and type definition improvements across two repositories. In mdn/browser-compat-data, updated compatibility data to reflect support for input type="week" on iOS Safari 18.2 and later, ensuring developers relying on MDN have accurate, up-to-date information. This involved careful alignment with evolving web standards and browser features using JSON and TypeScript. In grafana/k6-DefinitelyTyped, addressed a critical bug in the Range class by correcting the return values of comparison methods, thereby improving the reliability of TypeScript typings for k6 integrations. Demonstrated attention to detail and adherence to best practices in browser compatibility and type safety.
