Summary
#

  • Currently Cloud Engineer / Cloud Consultant at CloudNation. I have experience in several different areas of IT. Passion for scripting/developing. I love being challenged as it makes both you and the other grow, and helps to improve processes. I've taken up bushcraft as a hobby, and I am also a volunteer for a bushcraft organisation, where I'm supporting the instructors during courses, as well as learning new things along the way, every time.
