Developed the ProtoDuck extension for DuckDB, enabling direct deserialization and querying of Protocol Buffer messages stored within database columns. This work, integrated into the duckdb/community-extensions repository, focused on enhancing data interoperability for analytics pipelines that rely on protobuf-encoded payloads. Leveraging Rust for extension development and applying expertise in data serialization and database development, the solution reduced the need for external ETL processes by allowing users to access and analyze protobuf data natively within DuckDB. The project demonstrated a modular approach to extension design, supporting broader analytics workflows and facilitating more efficient data lake operations involving Protocol Buffers.
