    "If you are looking not only for a developer but also for a freelance CTO, look no more. He is very knowledgeable and more important, will look for solutions and best practice, even when it doesn't falls under his domain of expertise. He can run a project with minimal supervision or direction. I am very satisfied for making the right decision of hiring this guy. We will definitely work again on other projects to come. Thank you!"
