PROFILE
Gregory Croisdale
Over eight months, contributed to the hazelgrove/hazel repository by building and refining core features for the Hazel language and editor. Work included overhauling the Livelit system for safer, more reliable live literals, modernizing the initialization workflow, and expanding real-time collaboration through WebSocket-based multiplayer. Leveraged OCaml, TypeScript, and JavaScript to implement robust type systems, improve error handling, and streamline UI interactions. Enhanced data persistence, modularized build systems, and improved documentation and test coverage to support maintainability and onboarding. Focused on code quality through systematic refactoring, removal of deprecated components, and targeted bug fixes, resulting in a more stable, extensible codebase.

Mar 1, 2025March 2025 focused on delivering user-facing Hazel features, improving documentation and error reporting, and stabilizing tooling. Key outcomes include a refined Livelit projection system with segment-based handling and simplified invocation, comprehensive Hazel language docs, and a deliberate removal of Livelit from Init.ml to reduce risk and prepare for future rework. These changes drive developer productivity, better error diagnostics, and a cleaner, more maintainable codebase for the Hazel project.
