I’m building an e-commerce store on WooCommerce and need an experienced PHP developer who can handle everything from database logic to the customer-facing interface. The codebase is WordPress + WooCommerce, so you’ll be working with core PHP, hooks, templates, and REST API endpoints while also shaping the front-end experience. Key goals • Extend or create plugins that add store-specific functionality without bloating the site. • Tweak or build a lightweight theme/child theme so pages load fast and remain fully responsive. • Connect payment, shipping, and any third-party services through clean API calls, documenting changes in the repo. • Harden security, optimise queries, and make sure checkout remains smooth under load. Acceptance criteria • Features delivered as installable plugins or documented theme code, following WordPress coding standards. • No PHP warnings/notices in WP_DEBUG mode. • PageSpeed Insight mobile score ≥ 90 on critical pages. • All new endpoints return valid JSON and pass simple unit tests. If you have a track record of full-stack work in WooCommerce, can commit clean Git-based pull requests, and enjoy turning business ideas into production-ready code, I’d love to collaborate and ship this store together.
