Hello, My name is Sergey Korostelyov. I'm a developer from Russia. I believe that my strongest qualities are analytical mental structure, ability to work fast and effectively and high work responsibility. I think the main things every developer and especially a freelancer must think of is how to meet client expectations and of course deadline. I'm honest and fair. In 2006 I've graduated from Kharkov National Aerocosmic University and gained bachelor of computer sciences degree. I have over 3 years of C++ development experience. Most of that time I was working for 2 large Ukrainian IT companies and as a result I have almost nothing to show in my portfolio as I've signed NDA. From 2014 I had a remote work for company which preffered using Qt to write crossplatform applications. Since that time I have developed crossplatform video capturing/recording application from scratch and delivered it to client. Also I've participated other small projects at this time. Below you can see the list of technologies, frameworks and skills I have experience on: Thank you in advance for your time and consideration. Looking forward to work with you.
