About me
I have been fascinated by the world of IT since I was a child. At an early age, I began taking computers apart, repairing them and building my own networks. This passion motivated me to pursue a career in IT - an area in which I specialized in both server and network systems and innovative IT solutions.
After graduating from high school, my path led me to the Hamburg vocational school, where I successfully completed my training in the IT field.
During my time at Acer, I gained valuable experience in IT hardware and technical support. I then moved to the Helmut Schmidt University, where I was responsible for the implementation and administration of complex IT systems.

I am convinced that technology can be not just a tool, but a real competitive advantage when used correctly. This is exactly what I help my customers with: finding solutions that meet their individual requirements, be it in the area of virtualization, networking or storage solutions.
I look forward to continuing to contribute my knowledge and experience to exciting IT projects.
