Linux System Administration
I'm Linux administrator and systems architect since 2002. Most of my professional career is with design, setup and devops of medium and high loaded web farms, NoSQL databases which are time critical and require 24/7/365 uptime.
During last several years I'm concentrated on architect & administration of Hadoop ecosystem, NoSQL databases and clustered file systems as Cassandra, Riak, Ceph, ElasticSearch, GlusterFS.
I have big experience with variety of web servers and load balancers (Apache, Nginx, HAProxy, Tomcat, Jetty etc .. ) as
