It was a great experience working with Christian on a web application project. The Web application was developed in .Net and it integrated with a SQL Azure backend. He also developed a REST API layer for this application. Upfront he asked all the right questions, shared samples of prior work and provided guidance on the best approach for development. He exceeded my expectation from a quality and timeline perspective. He is very flexible and easy to work with. I would certainly work with him again and highly recommend his services.
