In my practice, I was able to get acquainted with the different technologies, programming languages and projects. I got all my skills in real production. I like my job and I want to be helpfull. My professional way started with implementation of a keylogger driver (using C for the kernel mode part and C++ and WinAPI for the user mode part). Then I worked on web management tool and implemented some features on server side for EkranSystem (employee monitoring system). Then I implemented Android applications Cloudifile and Cloudifile Pro (Dropbox data encryption system). Also I participated in a forensic project where I implemented parsers for iOS and Blackberry databases and a GUI using QT and QML. Besides, I developed a browser for Android based on chrome. I wrote new features and fixed bugs. I like working in team, but I can working successfully by myself. I have a deep experience in working with inherited code.
