Developed a native Stata .dta file read/write extension for DuckDB, enabling seamless data exchange between DuckDB and Stata formats 117 through 121. The work, contributed to the duckdb/community-extensions repository, focused on end-to-end I/O, allowing users to import diverse Stata data types into DuckDB and export query results back to Stata while preserving value labels and type mappings. Implemented in C++ with expertise in DuckDB internals and Stata file handling, the extension included comprehensive documentation to guide users. This feature reduces ETL complexity and enhances interoperability, supporting analytics workflows that require round-tripping data between Stata and DuckDB.
