Hi, I'm Joost.
With over 20 years of experience developing and maintaining scalable systems, I help manage software projects and design for change.
Joost is amongst the best I have met in my field so far. He knows how to drill down to the essence of things in a non-presumptuous and knowledgeable way, while leaving enough room for argumentation. He has an open mind, and is respectful to other opinions.
Working with Joost is a pleasure. He always knowns to ask the right thought-provoking questions, and his suggestions are well substantiated. These qualities made Joost a great addition to our development team. I would not hesitate to ask him again for another project.
Joost implemented a clear development process that supports a culture of delivering quality code and business value, and formed a productive, effective and loyal team.
Joost is a person with a creative mind and a wide area of interests. With his structured approach and impressive technical skillset he has helped our multi team organization to bring our delivery pipeline to the next level. He is also very pleasant to work with and the first one I would think about to hire again for other projects.
My relationship with Joost Cassee has benefited me and my projects beyond expectation. The process that Joost advised on helped transform development teams to become more self-organizing, cross-functional and autonomous. Joost is a product thinker with an innovative and Agile mind-set. He has incredible knowledge and uses this in a respectful way to team members and other stakeholders.
