With more than 25 years of experience in IT, I have built a broad background in software development, technical architecture, and team leadership. My career began in ERP development and evolved into consultancy, integration projects, and strategic technological advice. I enjoy collaborating with teams, supporting them in their development, and believe strongly in knowledge sharing and a pragmatic approach. Throughout my career, I have led teams both regionally and internationally and contributed to the standardization of working methods. I have supported companies in digital transformation, focusing on cloud technologies, data, and integration solutions, always with an eye on what is most feasible and beneficial for the business. I hold quality in high regard. Since 2024, I have been active as a freelancer, applying my experience to serve clients. I feel at home in environments where collaboration is central and where strategic thinking is combined with a hands-on mentality. My focus is on helping teams and organizations use technology effectively to realize sustainable solutions together. I see myself as a team captain rather than a coach giving instructions from the sidelines; as such, I am always happy to get my hands dirty.
