Bob developed a security-focused SQL extension for the duckdb/community-extensions repository, enabling OAST domain validation, decoding, and extraction directly within SQL queries. He implemented the extension in pure C, leveraging DuckDB’s stable C API to ensure seamless integration and performance. By embedding OAST domain analysis into SQL workflows, Bob’s work allowed security testers to perform in-database validation and detection of out-of-band interactions without leaving their query environment. This approach streamlined security testing processes by reducing context switching and supporting efficient data validation. The project demonstrated depth in C programming, SQL, and security testing, addressing a specialized need in database security.
