Over last 10 years I've been working in the enterprise environment, mostly in finance and telecoms. I'm expert in Linux administration (RHEL and Debian-based distributions) and have a very solid experience with HP-UX and enterprise hardware. My favorite field of work at this moment is covering a design and administration of complex, highly-available clustered systems, involving virtualization, shared storage with distributed file systems and load-balancing. I also enjoy challenging troubleshooting tasks, involving deep level debugging and tracing.
