Matt Corley developed and launched the ADBC DB-API engine for the marimo-team/marimo repository, enabling SQL connections through Arrow ADBC as a first-class engine with catalog discovery and dialect inference. Using Python and C++, he implemented arrow-native result fetching and schema-aware discovery, supporting scalable analytics across multiple SQL databases. In apache/arrow-adbc, Matt improved PostgreSQL driver reliability by removing search_path dependencies, ensuring consistent schema filtering for GetObjects. His work demonstrated strong data engineering and database management skills, with comprehensive testing and code quality practices. These contributions established a robust, extensible foundation for cross-database interoperability and future database adapter development.
