My previous experience includes working as a laboratory assistant at the College of Electrical and Computing Sciences, in GP Auto Shop d.o.o company as a system administrator and in Coming Computer Engineering d.o.o. as a system engineer. As a laboratory assistant I was teaching students taking lower level courses about basic functionality of computer networks. Working at this college helped me improve my leadership skills and my knowledge about the field I am currently working in. My second and third jobs require maintaining and improving current infrastructure based on Microsoft technology. Improving the current infrastructure involves dealing with the client working stations, server computers (Domain Controller, Remote Server, SharePoint, SQL server), adding new computers into a current network, establishing PPP connections with long distance using MikroTik routers (PPTP, L2TP, Ipsec etc.). In addition, the use of MikroTik routers requires the safety implementation (Firewall, Hotspot). Working in this field helped me realized that IT requires constant improvement in order to be successful. Therefore, I applied for a Cisco academy and passed Cisco CCNA test. In addition, I received Microsoft certificate MCITP 70-640 Administration Active Directory. In the near future my goal is to obtain more Microsoft certificates (70-642, 70-646, 70-662, etc), and also MTCNE MikroTik certificate. I am currently studying for the 70-642 certificate. I believe that my experience and consistent desire to excel will make me a valuable candidate for this position. I may be reached to arrange an interview through email or the numbers mentioned above. Sincerely, Marko Jovic

I am a professional software engineer, programmer, developer, Unix/Linux expert. I have many years of experience in programming, computer systems maintenance and machine languages. When I work I always do my job using a machine language and when I can't find one that suits the problem I create my own. I am also a maximalist. I always try to find the simplest solution, write the cleanest code, seek the best implementation.
