Worked on the SiliconLabsSoftware/matter_extension repository, focusing on maintaining and upgrading the matter_private submodule to ensure ongoing compatibility and build stability. Over two months, delivered targeted dependency updates by tracking upstream changes and integrating the latest commits, which reduced code drift and positioned the project for future Matter component integration. Employed disciplined Git workflows, including precise commit management and thorough pull request documentation, to maintain clear project history. Validated build and continuous integration integrity after each upgrade, demonstrating proficiency in submodule handling, release engineering, and dependency management. Utilized C++, Git, and CI/CD pipelines to support robust and reliable software delivery.
