Testimonial

Client's Review

Don't just believe what I say. See what others say about me.

Niels assisted the Heijmans project team with the implementation of the new meter replacement project at Liander. Both Liander and Heijmans are very satisfied with the implementation. He provides structure, solves problems, and interacts pleasantly with management and customers. In addition to implementing the new project, he has an eye for future improvements to the system. For example, the system performance monitor has been implemented, the planning system has been improved, and data security has been increased. In short: a skilled, independent professional who is a pleasure to work with.

Gertjan NoordstraManager at Heijmans

I have thoroughly enjoyed working with Niels. His expertise in Spring and Security is impressive. It is abundantly clear that he has a genuine passion for security. He enthusiastically shares his knowledge and ensures that we all remain alert in this area. Niels is also sharp and has an eye for detail in all other aspects of software development. This adds extra quality to the solutions we build. Beyond his professionalism, Niels is also a great colleague with whom you can laugh and have good conversations. He is definitely an asset to any team.

Calvin RichardsonSoftware Developer

Niels' knowledge of Java and everything that is going on in the world of Java is nothing short of impressive. He is able to pull people into the subject of Java, and guide them towards his level of expertise. Niels is a true asset to any development team; he is fun to work with, and he has a firm grip on code quality and security. I recommend him as developer and architect for complex and business-critical applications.
