Stefan Unterhauser enhanced the Teams feature in the open-learning-exchange/myplanet repository by refining the user experience for survey buttons, aiming to reduce friction during survey submissions. He focused on user-centric UI improvements within the Android application, leveraging Gradle for precise build configuration and version metadata updates. This work ensured smoother interactions for end users and improved traceability across releases by updating the build.gradle file to maintain compatibility. Although the scope was limited to a single feature over one month, Stefan’s contribution addressed a clear usability issue, aligning technical implementation with business goals and emphasizing disciplined release management and measurable product impact.
