"Hakan did brilliant work on a complicated plugin for which I had many peculiar and highly specific requirements." - Alan K., Professor of Literature in the U.S. "I can write a book review about the work Hakan did for me. He did absolutely everything I asked for and I couldn't ask for a more proficient, qualified freelancer. Will keep working with him in the near future.
