Summary
For over 20 years, I have been developing and taking responsibility for websites, shops, SaaS, learning, and membership platforms. My focus is on solutions where several systems need to work together reliably - from frontend and backend to payment, CRM and member management, APIs and automations.
I am the direct technical contact and implementer for companies, agencies, and product teams - from system selection and architecture through development and integration to ongoing operations. In existing teams, I support as a senior developer and architect with integrations, grown system landscapes, and demanding implementations.
