Summary
For over 20 years I have worked as a software developer and architect for custom software systems. I have worked in both product and project development, gaining a wide range of experience across the entire software lifecycle.
I am happy to support your team in:
- an early project phase through consulting (e.g. technology selection and technical feasibility) and assisting product management in setting up a team and agile methods
- as a technical project lead / coach / Scrum Master in agile software development teams
- analysis and design, system architecture, and software development
- reviewing existing systems and developing improvement measures, as well as carrying out major refactorings
Understanding customer requirements as the basis for developing a tailor-made solution is very important to me. Working at the interface between technology and business requirements has long been a key concern for me – IT should not be an end in itself, but should add value.
I like taking on new challenges, and I find it easy to integrate into new teams and contribute collaboratively. I also enjoy working in international teams.
