    Belarus - Last active: 12/02/2014 - Tests: 7 - Portfolio: 5

    The last 5 years I have worked mostly as a C and C++ developer in a field of process automation and control (SCADA). Familiar with OOP and TDD, Design Patterns and different methods of software development (waterfall, agile). I have a good experience in the development of multithread client-server applications, windows services, dll-s and cross-platform libraries. One of the specific features of my job was writing readable and easy-portable C-code covered with tests.Another interesting feature is working in small groups dealing with frequently changing goals. The major benefit of this style of work is a great experience on all levels of software development process (from project design and requirement development to final tests). Besides, I have a great interest in the research of new technologies and IT science related fields.
