Ofir Nachmani, CEO at IamOnDemand:

We've been collaborating with Kay since early 2020. During this time, he has written dozens of articles for us on a wide variety of tech topics. His technical expertise always shines through--he's even helped our clients debug their products along the way! He is communicative, deadline-driven, flexible, and extremely pleasant to work with--a true techie, writer, and a great guy.

An Editor:

Your writing is amazing, particularly for someone whose first language is (I assume) German. When I see that a job assigned to me was written by you, I always breathe a huge sigh of relief! [...] You are extremely meticulous about the small things that an editor needs to pay attention to [...] I almost thought you might be a native English speaker because your writing is so good and so colloquial.
