Worked on the aya-prover/aya-dev repository, delivering foundational enhancements to the Aya language’s type system over four months. Developed and overhauled partial type constructs, cofibration handling, and normalization, enabling more expressive and safer type-level features. Leveraged Java and functional programming to implement robust Abstract Syntax Tree manipulation, parser improvements, and type checking logic. Focused on maintainability through code refactoring, improved error reporting, and targeted test coverage, including stabilization of the test framework for reliable CI. Addressed edge cases in partial function evaluation, reducing debugging time and supporting future verification features. The work emphasized formal verification and type theory principles throughout.

Nov 1, 20252025-11 Monthly Summary for aya-prover/aya-dev: The month delivered substantial progress in the Aya type system and codebase stability, with a focus on business value and long-term maintainability. The team advanced partial type support and its integration with type checking, substantially improving safety and diagnostics for partial terms. In parallel, connection management was modernized with for-each loops to improve readability and maintainability of the codebase. A series of targeted parser, printer, and test fixes accompanied these changes, ensuring robust behavior as PartialTy features matured. Overall, these efforts reduce debugging time, increase reliability in partial-context workflows, and lay groundwork for broader type-system capabilities in future milestones.
