In 2018, I started working in the support department at Esri Netherlands. I cannot think of a better training ground for learning the craft of GIS. It was there that my passion for the GIS profession truly blossomed and my technical understanding of the Software both deepened and widened tremendously. However, after a few years, I wanted to focus more on tackling real world problems using GIS. So I started working for a Water agency in the Netherlands. Here, I was the connection between the System architects, policy advisors, ecologists and people in the field. I created webmaps, webapp, automated worfklows and managed servers. Growing into the organization, I noticed I became more and more involved in meetings and organizational processess and less with providing hands on solutions for actual problems. At this point I decided to become a Freelancer. My desire is to maximize the impact of GIS in any organization.
