9+ years experience, Senior backend developer. I can patiently explain the basics, as well as advanced topics
As a senior backend developer at one of the largest hosting providers in the Netherlands, I've written automated systems for our webhosting and VPS services.
I am also an active member of the PHP community in the Netherlands, attend a lot of meetups, try to help people in any way possible and trying out public speaking to aid that goal.

Dennis has been of great value from the very first second. He was very helpful, fast and to the point. He explained everything in detail where I lacked knowledge. He has a lot of experience and is very professional. Highly related and will call again when I want to learn something else.

Dennis sure knows his stuff. Very helpful. Excellent communication and really easy to work with. I'm most certainly going to work with him again.

The troubleshooting session for a very specific problem within my Dockerfile and app was answered with a lot more wisdom than I expected. Dennis explained every additional command which was unknown to me. He explained the flags and the purpose of commands and how they were chained. He is gracious and easy to collaborate with. He even equipped me with the right "train of thought" that I should use for solving Docker related problems, moving forward.
