Mia Zbikowski developed and maintained advanced theme tooling and schema validation features across Shopify’s theme-liquid-docs and theme-tools repositories. She engineered robust validation logic using TypeScript and JavaScript, introducing AST-based parsing and static analysis to enforce schema correctness and catch misconfigurations early. Her work included building a font deprecation checker, modernizing schema validation pipelines, and simplifying theme configuration by refactoring JSON schemas. Mia also improved documentation architecture and release management, aligning naming conventions and validation rules across code and docs. Through careful code organization and targeted bug fixes, she enhanced developer productivity and ensured more reliable, maintainable theme development workflows.

December 2024 focused on stabilizing release tooling and hardening configuration validation in Shopify/theme-tools. Delivered two major features: (1) Release management and release notes updates — changeset rename, version bumps across theme-tools, and up-to-date changelogs across two releases (04-12-24 and 10-12-24), including a missing changeset and manual changelog maintenance; updated 18 package versions in total. (2) Schema validation enhancements — added block_order case and static blocks content_for checks to catch misconfigurations and enforce static block definitions. This work improves deployment reliability, reduces post-release issues, and accelerates release cycles.
