I'm a senior Shopware 6 freelancer helping shop owners and agencies build fast, reliable, high-converting stores — from architecture to Shopware 6 upgrade.
Tech I work with every day
What I can do for you
As a former core developer, I know Shopware inside and out. I use this expertise to develop tailored solutions that sustainably advance your business.
Project Business
You want high-quality code and quick results? Let's go.
Whether you're a shop owner or agency – you need someone who thinks ahead, keeps up, and delivers. I'm your partner for Shopware 6 projects when you:
- want clean, maintainable code that scales
- need to get from idea to working prototype quickly
- don't want endless alignments but want to see progress
Shopware 6 Upgrade
Still on Shopware 6.6 or an older version? I'll migrate your store safely to the latest release.
I guide shop owners through upgrading to the latest Shopware 6 version — with minimal risk and no nasty surprises in the live store.
- low-risk upgrade process with a dedicated test environment
- compatibility check and adaptation of all plugins & extensions
- database migration, breaking changes & clean deployment
Plugin Development
Need custom features Shopware doesn't ship out of the box?
From small extensions to complex integrations, I build maintainable Shopware 6 plugins that follow best practices and survive updates.
- custom plugins built the Shopware way
- third-party & ERP/API integrations
- clean, documented, update-safe code
Technical SEO Audits
Great shop, but Google can't find it? Let's fix the foundation.
I run in-depth technical SEO and Core Web Vitals audits so your store ranks, loads fast, and turns visitors into customers.
- Core Web Vitals & page-speed optimization
- crawlability, indexing & structured data
- actionable report with prioritized fixes
