Frankfurt, Germany

I completed my three-year professional training at HM Buchdata in Frankfurt, a system house with a broad customer base in the non-profit and public sectors and the economy.

During my training I learned how to work in a structured way, how to deal with customers in a professional manner and how to respect experience. This demanded a lot of patience from my trainer, as I found other skills more important at the age of 15.

However, my experience in programming enabled me to automate some internal processes, accelerate migrations and support my colleagues. After graduation I left the company immediately due to several moral concerns.
