Worked on stabilizing the iOS build and deployment workflow for the openhab/openhab-ios repository, focusing on resolving persistent code signing issues that affected both CI and local environments. Upgraded Fastlane to a compatible version, refined Xcode project signing configurations, and integrated the 'abbrev' gem into the Gemfile to support build and deployment utilities. This engineering effort reduced release failures and streamlined the CI/CD pipeline, enabling more reliable and efficient iOS releases. Demonstrated expertise in CI/CD processes, mobile development, and Xcode configuration, with all changes traceable to a specific commit that addressed code signing and build tooling upgrades.
