    “Boyan is one of those extraordinary programmers who can do anything with code, and I am still amazed to see this project go from mockups to the real thing. What really stood out for me is the initiative he has shown throughout the project in filling in the blanks - by creating the sections I had not considered, so that things worked together seamlessly. I highly recommend him to anyone who wants to build large and complicated applications. Looking forward to working with him again. Thanks mate!”

    “MasterBo fixed my problem REALLY fast! His expertise was obvious as was his his professionalism. Whenever I need this type of system/programming service - I know where to go! MasterBo's ultra-prompt service allowed me to get my Moodle pages online in time for me to load and administer a test to my week-end students. He saved the day - the students are happy as the only alternatives were oral presentations.”
