Worked on the quarylabs/sqruff repository to enhance SQL generation by introducing a dedicated PostgreSQL Table Constraints Grammar. Focused on improving the accuracy and readability of generated SQL, the work involved designing and integrating a grammar that ensures named constraints maintain proper indentation, reducing the risk of misformatted DDL. Leveraged skills in grammar parsing, Rust, and SQL to refactor the generation pipeline, allowing for easier maintenance and extension of constraint types. The changes improved the maintainability of the codebase and facilitated faster onboarding for contributors by aligning the SQL output with best practices for formatting and parser design.
