Worked on the Infomaniak/ios-kDrive repository to enhance release build stability by addressing race conditions and UI issues. Focused on iOS development and UI/UX design, the approach involved reverting recent release-build changes that introduced instability, then validating the system’s reliability before further releases. Utilized targeted debugging to identify and mitigate race conditions affecting the user interface and overall app reliability. Emphasized clear documentation and communication of stability improvements to align the team on release quality standards. The work centered on bug fixing and release engineering, with efforts resulting in reduced flaky behavior and improved traceability in production builds.
