If you need scrapers/crawlers or related programming, you can't go wrong with Sergey. There are definitely cheaper people to hire out there. But if you want the job done properly from the outset with great follow-up, go with Sergey.

Not the cheapest coder around, but one of the best. Great communication, good software and more importantly delivered on time. No problem is too hard for him and he has great coding solutions to any issue. Would hire again no questions asked.
