Worked on enhancing ad-blocking capabilities in the uBlockOrigin/uAssets repository by delivering an improved Adblock-Compatible Link Shorteners feature. Focused on updating the ubo-link-shorteners.txt dataset and refining detection logic, the work aimed to reduce false positives while maintaining effective blocking of unwanted content. Leveraged skills in adblock development, filter management, and text processing using plaintext to ensure legitimate links were preserved and user experience was improved. Updated repository documentation and tracking to support future audits and rollbacks, contributing to the maintainability and auditability of blocking rules across the ecosystem. The work addressed both technical accuracy and long-term project sustainability.
