Summary

I have worked as an IT specialist for over 14 years and, after earning my degree in business informatics, I chose to move into consulting. With my strong communication and team-focused approach, I act as a successful link between development teams, clients, and project managers.

My main focus is on quality assurance for IT projects. I am dedicated to meeting defined quality standards, continually improving test processes, and enhancing development and operational workflows in a lasting way.

I have been part of projects across various industries – including automotive, telecommunications, and information technology – where I combined my technical skills with a clear understanding of business needs. My flexibility in location and my language skills also help me work effectively in international project teams.

What drives me is connecting innovative technologies with the real needs of users – to create IT solutions that are reliable, easy to use, and future-proof.
