Description

Are you looking for an experienced full-stack developer to implement your Shopware or Shopify project reliably and efficiently?

I help companies make their e-commerce platforms stable, performant, and future-proof – from individual plugins and complex API integrations to custom interfaces.

My added value for you:

- 8+ years of experience in Shopware and Shopify backend development

- Deep understanding of e-commerce architecture, performance optimization, and scaling

- Clean, maintainable code with a focus on long-term stability

- Direct, transparent communication and reliable project execution

Typical project outcomes:

- Development of custom Shopware and Shopify plugins

- Integration of external systems (ERP, CRM, payment & shipping solutions)

- Optimization of loading times and conversion-relevant processes

- Migration and upgrade of existing shop systems

Whether you're a startup, a medium-sized online retailer, or an enterprise client – I'll ensure your platform is technically on the next level.
