    Experienced IT specialist / Junior Web developer

    Ukraine - Last active: 22 days ago - Tests: 1

    I’m qualified IT specialist and junior web developer from Ukraine. Last 7 years i was working as IT specialist in different companies. The main task was to make stable IT infrastructure of the company and then support it. So now i have huge experience in networking, servers support, domain support, user support etc. Sometimes i had very interesting onetime projects. For example build a system for anonymous tests and then get a result (System was built using a few CentOS servers and ABBYY software). Summary about IT specialist experience: System administration (Domain controllers, DNS, DHCP, Mail etc.). Server administration (Windows server 2003-2012, CentOS, Windows XP/7/8). System monitoring (nagios, airwave, asemon etc.). Troubleshooting (solving different issues in existing networks). Networking (TCP/IP, HTTP, FTP, ip routing) Sometimes during my regular work i had to create some helpful things for myself. So i have tried to learn web development and web applications. For example:   -I have created useful app that is generating barcodes for inventory numbers and than creates PDF file with them.   -I have created phonebook for our company with internal/external phones + skype calls. The phonebook has authentication system that let you login as Admin to change info about any person. I know well the logic of MVC frameworks. Using official documentation i think i can do the most part of tasks. I'm using codeigniter, twitter-bootstrap, jQuery frameworks to create web applications. For some projects i'm using Wordpress framework.
