Client's review

Klaus Himmer
In a few weeks, CML Team could understand all the complex business logic behind our product and rewrite crucial backend parts in a proper solid way. They implemented missing functionality and polished the product to a production-ready shape. We have worked with them for over four years and are pretty happy with the agility, quality of the services, and insights they provide.
