Complex Custom Development

Custom WordPress Plugin and Theme Development

When an off-the-shelf plugin does not fit, I build what your business actually needs: custom plugins, WooCommerce business logic, theme architecture and third-party API integrations. AI speeds up the routine parts, and I plan, review and test the rest myself.

When do I need a custom plugin instead of an existing one?

When no plugin does exactly what you need, or when several plugins together slow the site or conflict. A focused custom plugin is often lighter and easier to maintain.

How do you plan a custom development project?

We start with a call about the goal, then I write a clear scope and quote. I build in stages so you can review progress along the way.

Can you integrate my site with a third-party API?

Yes. I connect WordPress, WooCommerce and Shopify to external services, and handle errors, security and data properly.

Do you use AI to write the code?

I use Claude, Gemini and ChatGPT daily to work faster, but I design, review, test and take responsibility for every line that ships.
