I’ve been in the Shopify ecosystem since 2019 — first with small shops and consulting, today as a senior developer for agencies, brands and enterprise projects. What hasn’t changed: I draw the data model first, then I write code.
IT training at 20, chapters in enterprise support and IT consulting, then step by step into the Shopify ecosystem from 2019 — and since then projects from one-person shops to international enterprise brands. I like both: the small pragmatic fix and the big clean system.
From service desk to enterprise project — every chapter a node in the network. The list keeps growing.

Agencies, merchants and teams I work with — quoted verbatim, in the original German.
