Summary

Over 25 years of IT experience, including 3 years in administration, networking, and firewalls.

Focus areas in recent years:

Customer and employee portals as web applications with backend systems in Java, .NET, and TypeScript.
Measurement and device data in industrial and automation technology.

Quality and functionality of applications for your company are my top priorities. I recommend architecture prototypes and Domain Driven Design to create balanced systems and avoid unnecessary technical effort.
