Jasper Abbink

Worked on the ReVanced/revanced-patches repository, delivering and maintaining ad-blocking and notification-enabling patches for the NU.nl Android app. Developed features such as ad removal and push notification enablement by manipulating bytecode and modifying Smali code, ensuring compatibility with evolving app versions. Applied reverse engineering techniques to update hook points and compatibility checks, preserving patch effectiveness across updates. Used Java, Kotlin, and Smali to implement and refactor ad-blocking logic, including adjustments for video pre-roll ads and JWPlayer integration. Focused on maintainability and traceability, consolidating changes into clear commits and reducing regression risk while supporting a seamless user experience.
