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.
Legacy Modernization
Your existing system is 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.
Voice & IVR
Voice portals, high-volume IVR, automated dialogs – a specialty for over 20 years. FreeSWITCH, Asterisk, WebRTC.
