Cortexley

Ecommerce Development

Storefronts built to convert, not just load.

We design and build Shopify, Shopify Plus, and headless storefronts — engineered for speed, merchandising flexibility, and checkout conversion.

Available worldwide — fully remote, timezone-flexible.

What is ecommerce development?

Ecommerce development is the design and build of an online storefront — merchandising, product discovery, and checkout — along with the performance work that keeps it fast under real traffic. Cortexley builds on Shopify, Shopify Plus, WooCommerce, and headless stacks, and has shipped live storefronts for fragrance, haircare, and eyewear brands.

Common questions

Both. We can extend a well-built existing theme or start from a blank canvas depending on your timeline and how far your current setup is from where you need to be.
