About

Meet Jonas Stenild — the developer behind the code

20+ years building for the web. Most of them deep in e-commerce.

Jonas Stenild

E-commerce Developer & Plugin Builder

I've been writing PHP and building for the web since 2005. Over the years I've worked deep inside Magento, Shopware, Symfony, and WordPress — building everything from full e-commerce storefronts to surgical backend plugins.

Today my focus is on building plugins that solve real problems for merchants and developers. I publish to the Shopware Store, WooCommerce marketplace, Shopify App Store, and Adobe Commerce Marketplace.

When I'm not building plugins, I work as a developer at Matas A/S — one of Denmark's largest retail chains — where I build e-commerce features at scale with PHP, Shopware, Magento, Symfony, and Vue.js.
