Summary

As an IT consultant self-employed for over 25 years, I’m used to working independently but also integrating into new and existing teams. In projects, I enjoy working pragmatically and goal-oriented. Daily learning is an integral part of my professional life, as are my commitment and sense of responsibility in all project phases. My free time I like to spend with family and friends who appreciate me for my reliability and honesty. I enjoy initiating sporting and social events but also value the quiet days within my own four walls.
