Vladislav RusanovVladislav Rusanov, System Engineer – Born June 20th, 1986 in Nikopol, spent his high-school years in Pleven and then studied Power Engineering at the Technical University, Sofia.

In 2005 he could experience the power of the console, and after that he became a devoted disciple of Vesselin Kolev who helped him gain notable control over the Machine. He, quite naturally, became Veselin Kolev’s right hand. Since then he has been irrevocably using Fedora as a working environment, and the servers he is in charge of operate basically on CentOS or RHEL, however no system has overpowered him yet. He hacks anything subject to disassembling. Besides, Vladi is a valuable staff member of the Sofia University Computer Center, where he deals mainly with routing. In this regard, and not without the influence of Vesselin Kolev, he is a real proponent of IPv6.

If he had a pet dog, he undoubtedly would call it Bash – further comment is hardly needed! Today, though the youngest member of the OPENINTEGRA team, he can, with his eyes closed, control virtual machines and certificate authorities, build and administer e-mail, DNS and hosting services. Gained experience and skills, pertinent to a few in this trade, trained by the best professionals, now himself one of them, Vladi is a loved and esteemed person by the OPENINTEGRA programmers staff, always ready to help whenever his staff mates encounter the immense vastness of the operating system.

As before mentioned, he is keen on hacking anything that may be disassembled, so not surprisingly he spends his free time on cars and all sorts of motor sports. He finds equal pleasure in both disassembling and controlling them, just like it is with the computers.
