Muhammad A.

WooCommerce Developer & Performance Engineer | Ex-Automattic

I help WooCommerce store owners fix slow stores, broken checkout flows, plugin conflicts, custom plugin issues, and complex API/integration problems. I previously worked as a Senior Software Engineer at Automattic, where I contributed to WooCommerce ecosystem projects involving marketplace infrastructure, vendor workflows, subscription activation, fulfillment integrations, plugin update systems, and production support tooling. What I can help with: • WooCommerce performance audits and optimization • Slow product, category, cart, checkout, and admin pages • Plugin conflicts, fatal errors, and hard-to-debug production issues • Custom WooCommerce plugin development • Payment, shipping, fulfillment, CRM, ERP, and SaaS API integrations • Inventory, order, refund, and subscription workflow issues • WooCommerce marketplace / multi-vendor architecture • WordPress/WooCommerce database, query, caching, and infrastructure bottlenecks • Refactoring fragile custom code into maintainable, production-ready systems Although some of my Upwork history is listed under front-end engineering roles, my broader background is full-stack: PHP, WordPress, WooCommerce, MySQL, REST APIs, JavaScript, React, Vue, Docker, Kubernetes, AWS, and Google Cloud Platform. Before Automattic, I worked as a software architect at an API integration platform, where I helped build integration infrastructure, two-way sync systems, automation workflows, and scalable cloud architecture. I am a good fit if you need someone who can go deeper than installing plugins — someone who can diagnose the actual technical problem, explain the tradeoffs clearly, and implement a reliable fix.
