Matheus De Sousa Bernardo
Worked on the ucsd-progsys/liquidhaskell repository to enhance Liquid Haskell’s type system, focusing on hole handling and synthesis detection. Leveraged Haskell and Liquid Haskell to implement typed hole support, refine warning controls, and improve error reporting, enabling safer and more productive hole-driven development. Expanded documentation and test coverage clarified user guidance and reduced debugging time. Consolidated ANF hole warnings and stabilized detection phases to improve reliability and maintainability. Addressed nested hole handling and migrated detection logic to reduce false positives, supporting robust synthesis scenarios. Emphasized code documentation, compiler design, and type checking throughout, contributing to a more reliable development workflow.
