Senior Backend Engineer & WordPress / WooCommerce Specialist for Hire

I'm a freelance WordPress developer who builds, scales, and fixes PHP-based platforms — the kind of systems that stop being simple once they hit real traffic. 7+ years leading WordPress, WooCommerce, and Magento architecture for teams that need more than a themer.

What I Actually Do

Not a themer. A backend engineer who specializes in WordPress.

Most "WordPress developer" listings mean someone who can theme a site and call it done. That's not this. I get called in when the problem is deeper than the front end: a checkout that breaks under load, a plugin architecture that's become unmaintainable, a site that fails Core Web Vitals no matter how many caching plugins get thrown at it, or a custom integration between WordPress and a CRM, ERP, or payment gateway that off-the-shelf plugins can't handle.

My work spans custom plugin development, WooCommerce and Magento architecture, REST API integrations, database and query optimization, server-level performance tuning, and security hardening — all built on PHP 8+, OOP, and SOLID principles, not patched together with page-builder shortcuts.
