K. Shannon engineered robust release automation and CI/CD improvements for the duckduckgo/macos-browser and duckduckgo/apple-browsers repositories, focusing on reliability and maintainability. Over five months, Shannon unified and modernized Fastlane-driven workflows, refactored monorepo GitHub Actions, and enhanced artifact management to streamline iOS and macOS release processes. Using Ruby, Shell scripting, and YAML, Shannon upgraded dependencies, automated tagging, and improved error handling, reducing manual intervention and release failures. The work included targeted bug fixes, such as stabilizing metadata uploads and optimizing git history fetches, demonstrating depth in automation, build management, and DevOps practices while enabling faster, lower-risk deployments across platforms.

February 2025 focused on stabilizing and accelerating release pipelines for the duckduckgo/apple-browsers monorepo. Delivered a Monorepo CI Workflow Refactor for iOS/macOS to streamline workflow references, directory contexts, and build triggers, plus Release Automation Reliability Improvements that upgraded the fastlane plugin and corrected git log/paths handling to improve task capture and artifact management for the last internal release. These changes reduce release failures, shorten cycle times, and improve traceability across iOS and macOS releases.
