Accessibility, performance
& reliable delivery.

I build new sites, solve live issues, and stay with the work after launch.

Read experience

I build, support and improve websites that have to work in the real world.

Web developer with 15+ years of experience helping businesses and agencies build, support, and improve websites. My deepest experience is in WordPress, alongside Shopify and more recent work with Astro and Next.js. My work covers production troubleshooting, custom functionality, accessibility, performance, and integrations.

I take work from technical investigation and scoping through implementation, QA, deployment, and ongoing support, with attention to reliability and maintainability.
