What I Actually Do

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

Most WordPress freelancers are strongest on the front end: themes, page builders, layout. That's valuable work, but it isn't what breaks when a business grows. What breaks is the backend. Orders stop syncing with the CRM, checkout slows down under load, and a plugin conflict takes the store offline on a Friday night.

That's the work I focus on. As a freelance WordPress developer, I take on scoped, senior-level engineering problems for store owners and agencies in the US, UK, Europe and Australia. You get architecture decisions explained in plain language, code built on WordPress and WooCommerce hooks (never core edits), and a clear written scope before any work starts.

How working with me works

Why clients choose a senior freelancer over an agency or marketplace

You talk to the engineer who writes the code. No account managers, no handoffs.
Senior judgment on small projects. A 2-week integration gets the same architecture thinking as a 100K-user platform.
Transparent pricing. Fixed-scope quotes and published starting rates. See how pricing works.
Selective availability. I take on a limited number of projects, so each one gets real focus.

Have a WordPress or WooCommerce problem nobody has solved yet?

Tell me what's happening and I'll reply within 24–48 hours with next steps. NDA available before we talk details.
