PROFILE

Omer Hadari

Worked on enhancing reliability and correctness in data processing systems, focusing on targeted bug fixes and code improvements across Rust and Python projects. In the influxdata/iceberg-rust repository, addressed a critical issue in predicate generation for date expressions, refining cast-date handling and expanding regression tests to ensure accurate query planning and maintainability. In the tobymao/sqlglot repository, improved the robustness of source expansion by standardizing table name normalization and ensuring callable sources are properly invoked, reducing edge-case failures in mixed-source workflows. Demonstrated skills in code refactoring, SQL parsing, and utility function enhancement, contributing to more stable and predictable data engineering pipelines.

March 2025 focused on stabilizing source expansion in sqlglot, delivering a targeted bug fix that improves reliability and consistency across lazy and non-lazy sources. The change standardizes normalization of table names and ensures callable sources are invoked to retrieve query objects, reducing edge-case failures and aligning behavior across provider types. This work lays a stronger foundation for robust query construction in mixed-source workflows and improves overall developer and user trust in the expansion process.
