During my 10+ years in software development, I have accumulated a solid experience working with various software technologies and programming languages. My career started while I was still studying in National University of Radioelectronics, where I got my Masters degree in Computer Science. At the moment I am focused on mobile applications development for iOS and Android. I have been working on iOS applications since the very first iPhone SDK was introduced in 2008. I am extremely detail-oriented and pro-active. I am not simply "providing development services" I solve problems for customers. I manage a team of software developers and I know how to get things done. I have a taste for good design and smooth user experience. A significant part of my career was dedicated to game development. I have an experience in creating solutions that are rich in graphics and have fluid animations. I am convinced that for a good developer it is not important which technology or programming language to use. He can work with anything. The list of the programming languages I know at least on intermediate level includes: Objective C, Swift, C/C++, Java, C#, Javascript, Ruby, Bash, Python. I have even dealt with such an old monsters like Visual Basic and Pascal.

Main specialization – C++ (STL/MFC, QT, PostgreSQL - on board). 15+ years of experience. Open to start new project on following tech stack: 1. Web: Python (any web framework), React, React-Admin, PostgreSQL, Dockers, Amazon Web Services, FreeSwitch. 2. Desktop, client/server solutions: C++, QT Framework. Last few years work with C++ on Debian (PostgreSQL, ncurses, thermal printer). Recently extensively switched to QT framework (Music Score scanning software). Had a chance to use general logic experience to lead engagement projects in completely unknown for me areas like Lotus Notes/Domino, software for greenhouse heating systems construction, some projects on Delphi. Searching clients for cooperation to outsource software products development. My formula: Scope of Work – Time – Budget (W-T-B). W-T-B key principles: - establish project required development process; - define milestones; - provide “access points” for process control from a client side; - self-documented code; - quality assurance; - support.
