Shopware Experts in Germany

• Project management of the legal and system-side integration of Taschenkaufhaus into the Voxa group: conversion of all contracts, accounts, and system access rights on the defined cutover date
• Migration from Microsoft Dynamics NAV 2009 to 2013: analysis of all existing interfaces, redefinition of processes, and coordinated go-live without interrupting operations
• Integration of the complaints and returns process into MS Dynamics NAV 2013; major process simplification through standardization
• Introduction of a new POS system (Shopify POS) in all stores: requirements analysis, configuration, rollout, and employee training
• Use of n8n automation workflows for data reconciliation between marketplaces and ERP; manual processes significantly reduced

• A digital system made up of special software and hardware components. The overall system replaces the traditional process with job slips and handwritten notes and enables more efficient order intake. Orders and work steps for the violin-making company’s projects can now be recorded, processed and logged in real time directly on the workshop’s touchscreen PC, by mobile phone or on the desktop. This gives customers a more transparent view of the work on their instruments and allows them to track the status and progress of their instrument through their customer account.

A little about me: I have been self-employed as a freelance copywriter since January 2017 and have found my personal passion in this field. Before that, I already worked as a copywriter in a permanent position at an advertising agency, where I was responsible for writing copy for major clients such as Zalando and Otto.

The step into self-employment was primarily for my own growth, not least because of the constantly new challenges. Today, my range of services includes the following:

• SEO texts
• product descriptions and product texts (Google SEO, Amazon SEO, Amazon+)
• website texts and category texts
• classic advertising copy / PR
• flyers, catalogs and brochures
• blog posts and editorial articles
• metadata optimization

As part of regular training and through relevant specialist reading, I naturally keep up to date with industry developments (especially in the SEO field, and now also AI) — both with classic Google SEO and for specific platforms such as Amazon.

Past and current clients include, among others:

• Trusted Shops Magazine
• Fielmann AG
• KLUGO
• Pinkbus
• #sinob
• Eucerin
• Hess Klangkonzepte®
• DogUniversity
• Beauty Concept Shop
• SmartXplain (here, among others, copywriting in cooperation with REWE, BASF)

Billing is subject to VAT via tax number and invoice. As a rule, I work with my hourly rate; for recurring projects, fixed prices per text are also possible. Of course, we can also discuss this personally — either via direct messages here, by email, or by phone.

Even in times of artificial intelligence, my focus remains on my craft. I use AI as support for organization, but I do 100 percent of the copywriting myself.

I look forward to your inquiry!
