About me
About 7 years I worked as system administrator at a company that provides SaaS-service from Microsoft and Linux/Windows VPS-service. Part of my job is related to the migration of customer services "in the cloud". I also have extensive experience in the installation and support VOIP-based systems (Cisco, Avaya, Asterisk, Freeswitch, etc).
