Joost Cassee

Joost provided clear practical insights and conceptual inspiration for the Bachelors students Information Management of our Open Data Course.

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 highly experienced developer. He excels in finding and implementing creative and innovative solutions. Because of that he added true value to our team and to the product.

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 is attentive to both people and technical details. He asks the right questions, finds fitting solutions and crafts the beautiful software you expected.

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.
