How we work:

As the biggest marketplace for special items, Catawiki operates in a domain that brings plenty of unusual challenges and opportunities.

We do this by using Infrastructure as Code principles, collaborative peer-reviews, Continuous Delivery, A/B testing every assumption and using the observability and monitoring tools already in place. We make mistakes and learn valuable lessons from them. Our focus is to be able to recover and iterate quickly.
