PROFILE
Stew O'connor
Worked on the unisonweb/unison repository, delivering backend and infrastructure improvements focused on reliability, maintainability, and developer productivity. Over five months, contributed features such as TLS socket equality enhancements, robust client/server configuration for TLS, and modernization of CI/CD workflows by migrating from Cabal to Stack. Applied Haskell and Shell scripting to refactor APIs, enforce stricter input validation, and streamline build pipelines. Improved code quality through formatting, documentation updates, and removal of technical debt. Strengthened cryptography APIs, expanded test coverage, and enhanced proof validation workflows, resulting in clearer API contracts, safer development practices, and more reproducible builds for the project.

Jan 1, 2026January 2026: Improved API reliability by strengthening the Update Verb input validation. Refactored the update verb schema to remove the 'oneOf' type and enforce exclusive input of either sourceCode or filePath (but not both). This clarifies the API contract, reduces invalid requests, and improves downstream processing. Implemented in the unison repository with a focused commit.
