I'm a professional with 10+ year background in IT, from system administrator with skills of programming and QA to system architect and R&D expert. Builded various platforms to solve problems of small bussines and Enterprise. I have a strong grasp of computer security (when dealing with Internet-facing or business-critical systems), ability to quickly and correctly diagnose what is wrong and how best to fix it. My comprehensive knowledge of hardware, software, application, and systems engineering helps me to preventing break-ins and other security problems with preventive measures. Understanding of the behavior of software in order to deploy it and to troubleshoot problems, makes me good at problem solving (frequently under various sorts of constraints and stress)
