Fan Yang

Worked on the duckdb/duckdb-go repository to enhance API readiness and reliability over a two-month period. Focused initially on refactoring internal type names, aligning 'conn' and 'stmt' with their exported counterparts to improve code clarity and maintainability in Go. This groundwork supported future API exposure and streamlined contributor onboarding. Subsequently, addressed error handling in the statement lifecycle by unifying error messages, removing inconsistent wrapping, and increasing test coverage for edge cases. Leveraged skills in Go, database integration, and testing to standardize error checks, reduce debugging time for downstream clients, and ensure the codebase remains robust and easier to maintain.
