Worked on Shopify/theme-tools to enhance developer tooling and theme maintainability by delivering three new features over two months. Developed cross-file references and document linking for JSON and Liquid schema in the language server, improving navigation and code analysis for theme developers. Added an orphaned snippet check to identify and prevent unused code, strengthening code quality. Implemented Liquid HTML parser support for snippet tags, including both CST and AST stages, ensuring accurate parsing and robust error handling. Leveraged TypeScript, JavaScript, and the Language Server Protocol, with a focus on parser development, static analysis, and test-driven development to ensure reliability and maintainability.

Sep 1, 2025September 2025 (2025-09) monthly summary for Shopify/theme-tools focused on delivering developer tooling enhancements and code health improvements that drive business value and long-term maintainability. Key features delivered include Theme Language Tools Improvements (cross-file references in the language server, document linking enhancements for JSON and Liquid schema, and Liquid parser enhancements) and the Orphaned Snippet Check for Shopify Themes (a new theme check to identify orphaned snippets and prevent unused code). Major fixes included aligning tests and refactors around JSON language service instantiation and updating test cases to match document linking changes. Overall impact: improved developer productivity through richer navigation and references, higher code quality by catching orphaned snippets earlier, and a stronger baseline for future theme tooling. Technologies/skills demonstrated: TypeScript/Language Server Protocol, JSON/Liquid schema parsing and linking, test-driven development and test infra refactoring, and maintainability through shared type definitions (theme-check-common).
