I go with you through all the stages of development. My strong skill is solving non-typical programming tasks that need ingenuity and persistence. If you have a problem that nobody could help you with, then you found a right man. I'm a freelancer for 15+ years and have expertise in a lot of technologies. Some of them follow: - C#, ASP.NET, Mono, Xamarin, Python, PHP, Perl, C++, C, javascript, SQL, regex, VBA, HTTP, SSL; - data parsers/processors/migration tools; - system programming for Windows, Linux; - network traffic proxies, monitors, modifiers/encoders based on NDIS, TDI drivers, LSP, hooks; - mathematics modeling, calculus of approximations;
