Summary

For over 30 years I have supported software projects from analysis through architecture and integration to production rollout. This includes both existing systems and new applications, prototypes and MVPs. I focus on technically clean and maintainable solutions. I work pragmatically, taking on architecture and implementation together, and move confidently between business needs, system design and hands-on coding. My main stack is Java. I also work with Angular, Flutter/Dart, JavaScript/TypeScript, XML, REST, messaging, databases, containers and CI/CD. I use modern tools and AI-assisted development pragmatically. My goal is systems that fit the business, stay technically understandable and run reliably in operation.
