Konstantin was a great strategic partner during our development project and delivered an excellent product exactly according to specification, using the latest in modern web development. His great communication skills meant frequently checking in, asking clarifying questions as well as providing pro's and con's of each development option. I would recommend anyone to work with Konstantin!
