    Please do not create personal project for me - instead create project with detailed description and proper project name and send invite. I do not develop kodi or enigma addons/plugins! I do not work via teamviewer for projects with cost < 200$ I'm working as system administrator at ISP more than 11 years. I have experience with linux more than 12 years, it includes firewall,raids, any typical services (like apache,nginx,exim,dovecot,ejabberd,samba, etc), backups (bacula, rsync), monitoring (custom scripts, nagios, cacti, zabbix, munin). I have 5 years good practice with voip, 3 years experience with asterisk, also I developed voip traffic analysis app for gathering statistics from rtcp packets. I use python for my work automation (scripting). I can setup home routers, voip adapters, switches (dlink, low models of cisco, huawei), some low experience with routers alcatel sr, juniper erx. I'm also interested in short project with programming in python, delphi, c, php under linux. меньше
