Developed a Custom Index Management API for the viamrobotics/api repository, focusing on enabling create, list, and delete operations for custom indexes. The work involved designing Protocol Buffer definitions, including enums and messages, to standardize index operations and ensure compatibility across different clients. Leveraging Go and Protocol Buffers, the developer established a gRPC service surface and implemented HTTP gateway mappings, allowing the API to be accessed via both gRPC and REST interfaces. This approach facilitated cross-language client integration and laid the groundwork for future index-related features, emphasizing maintainability and extensibility in API development without addressing bug fixes during this period.
