    Michal was a realt pleasure to work with. His communication skills are great when working with him on Skype or via email. His time management is excellent, setting expectations correctly for delivery of features. However, that all is all outshined by his ability to clearly communicate issues, suggest better approaches to achieve business goals, and suggest technologies that can speed-up projects or lead to better results. He is a Class-A Ruby on Rails engineer. I've thoroughly enjoyed working with Michal and highly recommend him for your next project.
