About Me

For nearly 20 years I’ve been creating and evolving different digital infrastructures. From a basement rack to multi-cloud. I have IC, EM and PM experience, understand how businesses work and able to find appropriate solutions. I like meeting colleagues on-site and used to remote-first, cross-timezone work.
