Worked on API maintenance for the spacetelescope/catkit2 repository, focusing on streamlining the service API by removing obsolete protobuf attributes from service.proto and eliminating the unused m_PropertyDataStreamLinks member from ServiceProxy.h. This cleanup reduced the API surface area, aiming to minimize maintenance overhead and clarify the interface for downstream consumers. The approach emphasized clean code practices and disciplined code refactoring, leveraging C++ and protobuf schema definition skills. While no user-facing features or bug fixes were released during this period, the work improved API clarity, reduced potential confusion for integrators, and laid groundwork for easier onboarding and safer future refactoring efforts.
