Summary
For more than 20 years, I have been developing and taking responsibility for websites, shops, platforms, and automations. I have worked as a Senior Software Developer, Solution Architect, Tech Lead, and IT Manager.
For companies without their own tech team, I take on full technical responsibility: from requirements analysis and system selection to development, integration, and stable operation. In larger teams, I focus on software architecture, interfaces, and demanding integrations.
My focus is on digital platforms whose parts must work together reliably - for example websites and shops, payment, CRM, learning and membership areas, as well as APIs and automations.
Selected results:
- WordPress/WooCommerce: took over, secured, and automated maintenance for 7 shops; developed a custom B2B ordering system for 3 companies and 14 locations
- Kajabi and learning platforms: sole technical contact for a platform with 30,000+ members and 15,000+ course customers; connected Kajabi, WordPress, WooCommerce, and Digistore24
- Wix/Velo: certified Wix Expert Developer; delivered membership, payment, CMS, API, and automation solutions as well as numerous websites with design partners
- Platform automation: automated onboarding for around 7,000 active members via Wix, Discord, TradingView, and MetaTrader
- E-commerce and technical leadership: 7.5 years at etikett.de, most recently as Tech and Team Lead for 6 international shops, ERP/MIS, Web2Print, AWS, and CI/CD
- Enterprise architecture: e-commerce solutions and workshops with Shopware, Spryker, Symfony, and APIs at best it AG
- AI platforms: developed a multilingual travel planning platform with React, Node.js, PostgreSQL, OpenAI, and a multi-agent system
Technologies: PHP, WordPress, WooCommerce, Wix/Velo, Kajabi, Symfony, Laravel, JavaScript, TypeScript, Node.js, React, Next.js, REST APIs, PostgreSQL, MySQL, MongoDB, Docker, AWS, and Vercel.
I join in at any stage: during a rebuild, targeted further development, or the technical restructuring of a grown system landscape. Existing solutions stay in place if they do their job. I develop or integrate missing features to fit the existing architecture.
