João is an Interim CTO for hire and a Strategic Software Delivery Consultant at Xebia. He focuses on helping teams and organizations to make strategic decisions regarding the software and aligning teams and software to optimise the stream-based value. He believes in the power of collaboration and is a fan of visual collaboration tools. He is the host of the Software Crafts Podcast. In his spare time, you can find him travelling with his daughter and wife, or laying down on the beach reading a book. João is also an amateur cook.

A lot of knowledge is lost when designing and building software — lost because of hand-overs in a telephone game, confusing communication by not having a shared language, discussing complexity without visualisation and by not leveraging the full potential and wisdom of the people. That lost knowledge impacts the quality and value of the software product being build. By leveraging Deep Democracy, Domain-Driven Design, Continuous Delivery and visual collaborate tools, Kenny Baas-Schwegler empowers organisations, teams and people in building valuable quality software products.

One of my core principles is sharing knowledge. I do that by blogging on my website baasie.com I also organise several meetups like Virtual Domain-Driven Design, Domain Driven Design Nederland, and I am a public speaker giving talks and hands-on workshops at conferences and meetups.
