If anyone is unsure if you should hire Stefan or not, let me tell you: He is a very bright man.
While I have not worked with him directly (yet – hopefully this will change in the future), we’ve had multiple very valuable technical discussions. I consider him to be a very smart and knowledgeable man.

So, consider this some kind of letter of recommendation!

I have worked with Stefan for a couple of years and could’t have said it better than Qqwy.
Stefan is dedicated, intelligent, responsible and takes pride in what he does and works very hard for it.
A real go-getter and not to forget…a very nice person as well.

So hire him. You won’t regret it.

Thanks Wiebe-Marten, much appreciated!
