Worked on the Eventual-Inc/Daft data processing framework, focusing on improving stability and correctness by addressing a projection pushdown bug affecting Source nodes and custom DataSource joins. Used Python and Rust to implement a guard that prevents modification of materialized scans and ensures complete column sets during joins, reducing production risk. Expanded regression test coverage with both Python and Rust unit tests, modernized the test harness to support async programming patterns, and collaborated cross-functionally to reinforce maintainability. This work provided a more robust foundation for future pushdown optimizations and performance improvements, emphasizing careful engineering and thorough validation over rapid feature delivery.
