Testimonials

I had the opportunity to review the code he wrote... I was very impressed with two things: first, the quality of the code. It was easy to read, well-structured, and nicely formatted. Second, it was clear that Jan not only knew about a lot of the more recently-added features of PL/SQL, but he knew how to put them to use. If you have the opportunity to include Jan on an Oracle Database development project, I suggest you do not hesitate to take advantage!

Steven Feuerstein

Jan is a knowledgeable person who is eager to help others. I am impressed in how much he keeps moving forward in a very fast pace. He really stands out of the crowd combining both great technical and managerial skills making him to a highly valuable Oracle developer.
