Worked on the uBlockOrigin/uAssets repository to enhance ad-blocking capabilities by developing and refining filter management features. Delivered an update to the Adblock-Compatible Link Shorteners, improving detection logic and updating datasets to reduce false positives while maintaining legitimate link access. Utilized plaintext and text processing skills to ensure the new rules were both effective and maintainable. Additionally, addressed a targeted bug by correcting a filter rule typo for dailymail.com, restoring proper ad-blocking functionality and site compatibility. Focused on clear documentation and commit history, supporting future audits and rollbacks while maintaining performance and stability across the ad-blocking ecosystem.
