Technologies and skills demonstrated - ESLint customization, inline SVG optimization, and frontend performance optimizations. - TypeScript migration and TS-based frontend code enhancements. - Integration with public APIs (postcode-validator) and regression testing disciplines. - Build tooling improvements (Sass, container queries) and WP 6.8 compatibility. - Feature-flag gating and dynamic UI composition for merchant workflows.

May 2026 focused on delivering a robust WooCommerce Store API skill, stabilizing testing, and aligning WordPress core imports for maintainability. Key work included a feature module for the Store API detailing route development, authentication, schema, and performance handling, plus substantial documentation updates aligned with RFC standards. In parallel, I fixed critical test and compatibility issues: intercepting redirects in Back in Stock Notifications tests to prevent PHPUnit halts, and refactoring Taxonomy type imports to the public WordPress core entrypoint to improve long-term compatibility. These efforts contributed to higher API reliability, clearer developer guidance, safer CI pipelines, and stronger integration readiness with core WordPress components.
