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.
Technical E-Commerce Consultant
A complete tracking foundation for Rimoco's Shopware 5 shop: GA4, Tag Manager, ads conversion tracking, Klaviyo flows, consent mode and a Looker Studio dashboard — plus Shopware 5 support and consulting for the relaunch on Shopify.
Frontend Development & Technical Consulting
Ongoing frontend development for the group's websites and online shops — including Amira Aly (Amiras Zauber), Einfach-Lecker (Stefanie Biedermann), the Einfach Backen shop and Decocino, the baking brand with collaborations including Sally and Stefanie Hertel. Further projects in the group: glytter.eu, nolatea and others.

Technical E-Commerce Consultant
Developed the technical concept for an online shop: requirements, shop architecture and clear recommendations for the implementation.

Shopify & Xentral Integration Consultant
Connecting Xentral to Shopify: product master data, variants, warehouse management and shipping processes — including a structured product data import with images and metafields.

Shopify Consultant
Audited the online shop and stayed on as an advisor — concrete recommendations for the tech and the day-to-day.
Website Migration & Ongoing Support
Migrating an existing website off an outdated PHP 5.0 system onto Wix: setting up the new site and training the staff to run it. Ongoing support since 2026.
Shopify Consultant
Not every project is allowed to appear here: I advise several corporations on Shopify on an ongoing basis — under non-disclosure agreements. Names, numbers and details stay where they belong: with the client.
Technical Consultant & Project Oversight
Accompanied the KnabeMalz release in the Ready2Drink shop: project oversight supporting the project manager — an eye on the tech, a grip on the progress.
Senior Shopify Frontend Developer

For micasa, Delica, CoffeeB, ooia, oh april, Bego Dental, hochbeet.com, Overkill, Snushus, Herbaria and Cosline Cosmetics, among others.
Senior Shopify Frontend Developer
Migration from a headless store system to native Shopify, built on the Horizon theme architecture — the existing design carried over in full, including every element.

The entry into the Shopify ecosystem: built and looked after small shops, advised merchants, tested themes, apps and variant logic in real setups. With the first bigger client came the final step into full-time.
IT Consultant
Consulting and project work at one of the world's largest IT service providers — for corporations and mid-sized companies across many industries. Enterprise projects, grown systems, many stakeholders.
Service Technician, then Junior Training Specialist
A chapter at a Media-Saturn Group subsidiary: first hands-on technical service, then passing the knowledge on as a Junior Training Specialist — close to the product, close to the customer, right inside retail.
Service Agent & Service Desk Analyst
First professional years in enterprise IT: solving user problems, narrowing down incidents methodically, learning the ticket systems and processes of large organisations from the inside. The school for what still carries today — listen, understand, solve cleanly.
Agencies, merchants and teams I work with — quoted verbatim, in the original German.
