Back to original languageAbout Daniel
Since 2018, I have developed over 70 websites and online stores, focusing on tailor-made e-commerce solutions and system integration. I don't just create stores; I develop full-stack architectures that deliver real added value – from the storefront to backend logic.
As a specialist in Shopify, Medusa.js, and backend development, I help ambitious e-commerce companies overcome their technical limitations. My expertise includes:
- Creation and configuration of Shopify stores, including B2B setup and multi-market setup
- Development of custom Shopify functionalities, App Proxy Services, and Liquid programming
- Custom e-commerce solutions with Medusa.js for complex requirements beyond Shopify
- Development of custom CMS solutions and tailor-made headless architectures
- ERP/WMS integration and development of custom merchandise management systems
- System integration (e.g., Sage ↔ Shopify Connector, DACH region)
- AI integration into existing systems – from intelligent search solutions to automated workflows with LLM connectivity
- Process automation with n8n, Airtable, Supabase, and other tools
- Node.js/Express backend services, GraphQL Admin API, HMAC authentication
- Migration of existing stores (e.g., WooCommerce) to Shopify or Medusa.js
- Custom calculators, configurators, and data-driven applications
What sets me apart: I don't think in plugins, but in systems. I develop scalable architectures that remain performant even with growing volume – and combine technical depth with entrepreneurial understanding of e-commerce processes.
If you are looking for a developer who goes beyond the standard setup and can connect technically demanding solutions with measurable business success, let's talk.
