PROFILE

Morisa Manzella

Morisa Manzella focused on improving code hygiene and reducing maintenance risk in the Shopify/theme-tools repository by refactoring the Liquid HTML parser. She removed the unused '@prompt' node, updating the parser’s grammar, abstract syntax tree representations, and TypeScript type definitions to reflect a leaner codebase. This cleanup also included eliminating related tests, which streamlined the test suite and improved continuous integration efficiency. Working primarily with JavaScript, TypeScript, and parser development techniques, Morisa’s targeted changes reduced the parser’s surface area and potential for regressions, ensuring that existing functionality remained stable while making the codebase easier to maintain and evolve.
