I've been a technician for years, and an artist longer than that. I'm also a musician, and have many videos on YouTube. I've been into social medial since the late '90s. Though I tend to keep my friends list on the small side, I do see a large impact from what I post.
My name is Sergey Pozdnyakov. I'm a software developer with 10+ years of programming experience. I have an expertise in very different areas, including: - Financial software and database programming - Embedded software for Linux- and RTOS-based devices (closed platform mobile phones, e-readers etc) - Mobile software for Microsoft platform - Desktop software for Windows, cross-platform desktop software created with Qt framework - Server software (VoIP) I'm an expert in C/C++, and have a very good knowledge of Perl and Python. Most of the software I created was for Windows platform, but I also had some projects for Linux and Mac OS X. I've worked for several international companies (American and European), so communication wouldn't be a problem. I've participated in creation of commercial software products, and I'm good with meeting deadlines. I worked in a senior developer position, and communication with customers in order to collect business requirements was one of my primary tasks, so I will treat every project very carefully and make sure that I have full understanding of customer needs.
Software developer with 3+ years' experience in Python/Django. Excellent at developing and maintaining client/server applications. I am experienced in software deployments, networking and Linux environments.
