Hi, I’m Jan. I design, build, deploy, and operate software systems. I especially enjoy working at the intersection of engineering and users, and I thrive in multi-disciplinary teams.
Currently, I’m a self-employed software engineer based in the Netherlands, with a current assignment at PwC in Amsterdam. Previously, I co-founded a startup focused on customs clearance, worked at a venture studio in collaboration with Port of Rotterdam, ABN Amro, and Standard & Poor’s, and completed my studies at Delft University of Technology in Computer Science and Aerospace Engineering.
Outside of work, I enjoy cooking, photogrpahy, staying active (running, cycling, hiking), and keeping up with the latest trends in software development.
