Services

Three things, done well.

Build

E-commerce builds

I design and build WordPress, WooCommerce and Shopify storefronts from discovery to launch, with accessibility and performance tested as part of delivery.

3D product configurators

I turn complex, configurable products into clear buying journeys—from product rules and 3D assets to pricing, stock and a valid purchase.

Grow

Performance, SEO & CRO

I audit the technical and commercial bottlenecks, fix the highest-value problems and verify the result against measures agreed before work starts.
