Worked on the mullvad/mullvadvpn-app repository to deliver automatic relay list management and build integration for the iOS app. Developed a build-time script using Shell and Xcode project configuration to fetch and embed the latest relay data into release builds, ensuring users always connect through current relays. Updated the relay list cache handling by relocating the cache and automating updates, which reduced manual maintenance and minimized discrepancies between development and production environments. Demonstrated skills in scripting, build system configuration, and cache management, resulting in a streamlined release process and improved reliability for relay data integration within the app’s CI/CD workflow.
