Profile and Services
I help SMEs and agencies make the right technical decisions – whether modernizing existing systems, designing new APIs, or integrating different platforms. With more than 25 years of experience in software development, I bring structure to complex projects.
From legacy system to modern solution
I support companies and agencies with technical decisions, system design, and project leadership – pragmatic and collaborative.
Good software isn't built with the latest technology – it comes from well-considered decisions. I like reducing complex problems to their core and finding pragmatic solutions that still work tomorrow.
Now that AI writes a large share of the code, language and framework matter less – experience and judgment matter more. AI is an integral part of my work: it takes over routine tasks and makes me productive quickly in unfamiliar codebases and stacks.
Web Applications
Self-service portals, internal tools, and platforms integrated with ERP, accounting, and payment providers – from concept to operation.
Legacy Modernization
Is your existing system showing its age? I analyze the status quo and develop a realistic migration plan – step by step, no big bang.
API Design & Integration
Clean interfaces are the backbone of modern systems. I design APIs that are understandable, extensible, and well documented.
System Architecture & AI
Before the first commit comes the concept. I help with technology selection, interface planning, and the meaningful integration of AI components – in structures that still hold up years from now.
Telephony & IVR
Voice portals, high-volume IVR, automated dialogs – and above all the bridge to billing, customer data, and web applications. A specialty for over 20 years.
Stacks and frameworks
Many languages, frameworks, and platforms over more than 25 years – the stack follows the project, not the other way around. A selection is listed under Technologies and skills (German).
Memberships
Member of the examination board for IT professions at the Chamber of Commerce and Industry (IHK) Mittlerer Niederrhein (Neuss)
