Mia Zbikowski

Mia Zbikowski developed and enhanced theme validation and tooling for Shopify’s theme-tools and theme-liquid-docs repositories, focusing on schema validation, release management, and code quality. She implemented AST-based parsing and JSON schema validation in TypeScript and JavaScript to modernize validation pipelines, introduced checks for deprecated fonts, and improved block ordering and preset logic to reduce runtime errors. Mia also addressed configuration missteps by refining validation logic and documentation, enabling more reliable and maintainable theme development. Her work included fixing false positives in block detection and supporting dynamic visibility, demonstrating depth in code analysis, Liquid templating, and cross-repository collaboration for robust tooling.

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.
