PROFILE

Alley Stoughton

Worked on the EasyCrypt/easycrypt repository, delivering features and fixes that enhanced type safety, API flexibility, and proof reliability. Exposed internal type policies and theory creation APIs, enabling external tools to perform type checking and manual theory management without loaders. Improved the require workflow for maintainability and future automation. Added lemmas for reasoning about list concatenation, refined operator pretty-printing for accurate parsing, and clarified error messages to streamline debugging. The work demonstrated expertise in OCaml, functional programming, and formal verification, with a focus on robust module design, code refactoring, and error handling to support both developer experience and tool integration.

January 2025 — EasyCrypt/easycrypt monthly summary. Key features delivered: - Exposed the tp_nothing typolicy from EcTyping in ecTyping.mli, enabling external tools to perform type checking and explicitly forbid type variables (commit bba51946f0b8a17a39878ecbd4875fa65ebb62d4). Major bugs fixed: - No documented bugs fixed for this month. Overall impact and accomplishments: - Strengthened external tooling integration and type-safety by making EcTyping's policy explicit in the public interface, paving the way for automated checks and safer interoperability with third-party tools. Technologies/skills demonstrated: - Interface design and module boundary exposure, type policy modeling, commit-driven development and version-control discipline.
