    “My first time on Freelancer and first time working with Sergey and without a doubt the best experience I could have ever expected! Not only was the delivery ahead of schedule, but with clear notes and detailed explanations I was able to understand the code with ease. I recommend Sergey without question to anyone new/old to Freelancer. Also a shout out to Barbara Brenner (Freelancer Staff) for outstanding support and professionalism and well worth the $20, especially for any first timers. Great Job!!”
