Employment and project overview

My highest school-leaving qualification is the Fachhochschulreife.
Between secondary school and technical college, I trained as a toolmaker.
After 4 semesters of mechanical engineering, I went into IT.
I started with a one-year apprenticeship as a technical computer scientist (CDI), followed by further training as a network engineer, and always with a lot of personal commitment.

I have been learning new things all my life and hopefully that will never end.

I was employed for most of my professional life, and for a few years I worked as a freelance IT consultant. 
I am not allowed to name my clients during my freelance work. 
I am happy to provide information on request.
