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.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).Therefore, I applied for a Cisco academy and passed Cisco CCNA test. In addition, I received Microsoft certificate MCITP 70-640. In the near future my goal is to obtain more Microsoft certificates and also Cisco CCNP certificate.
