Developed the Repository Manual Merge Settings feature for the wxiaoguang/gitea project, enabling configurable manual merge behavior at the repository level. This work involved augmenting the repository data model in Go to include AllowManualMerge and AutodetectManualMerge fields, ensuring these settings were consistently handled throughout data conversion processes. The API was updated to expose the new fields, providing clients with greater visibility and control over merge governance and automation. The implementation focused on end-to-end data flow, from model changes to API exposure, and emphasized traceability through clear commit history. Demonstrated skills include backend development, API design, and data model evolution.
