about
I am Thijs van der Velden, a freelance data engineer with over 10 years of experience. I design data platforms, define the architecture and build alongside the team: from the first sketch to a platform that runs in production every night. I also lead teams of data engineers, as tech lead or product owner, keeping technology and business aligned.
