Freelancer profile translated to English.
Back to original languageAbout Kevin
I support companies and agencies with ongoing technical issues related to Shopify, Shopware, and existing e-commerce systems – from technical support and problem analysis to the further development of existing shops.
My focus is on Shopify Theme Development, Liquid, JavaScript, TypeScript, as well as technical adjustments during ongoing operations. This includes theme customizations, new sections, product pages, app integrations, tracking with GA4 & Google Tag Manager, performance optimization, and technical troubleshooting.
I am often involved when existing shops need to be expanded, technically cleaned up, or pragmatically further developed – understandable, direct, and without unnecessary technical circus.
