Hi. I'm Marcel. I'm a freelancer, trying to help solve problems with IT. I have experience with organizations in the clean-tech and sustainability sector, most with EV charge-points and solar panels. I've worked on data analytics, on custom business line software, and on integrations with external services. I try my best to bring simplicity, clarity, and business-focus to the work I do.
