Worked on the modal-client repository to streamline API protocol definitions by removing the unused use_gapless_read field from the FunctionCallGetDataRequest message. This targeted cleanup reduced the API’s surface area, making future changes less error-prone and improving maintainability for both current and new contributors. The approach emphasized disciplined change management, with clear commit history and thorough documentation of the update. Leveraging skills in API development and Protocol Buffers, the work focused on refactoring and maintaining code hygiene rather than introducing new features or fixing bugs. The result was a cleaner, more maintainable proto-based API interface for the project.
