About
Meet Jonas Stenild - the developer behind the code
20+ years building for the web with PHP, Symfony, and modern JavaScript. Most of them deep in e-commerce plugin development and platform architecture.
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.
