My expert systems administration services are available on a limited contractual basis. You may review my resume here. These are the specialized niches I can build a project for you around.

High Availability

I have substantial experience implementing high availability systems and components, utilizing Storage Area Networks (SAN), fiber channel multipath storage, RAID, load balancers, Veritas Cluster Server (VCS), and other products. I can assist you in improving systems availability to meet stated service level agreements and uptime guarantees.

High Performance

I develop and implement monitoring systems for gathering and visualizing performance trends. These data can be leveraged to understand the root cause of performance degradation. I bring to the table valuable experience with Oracle RDBMS and Java application servers (ATG Dynamo and BEA Weblogic), among other things. See also: Monitoring Networks with Cricket

In addition, I have extensive knowledge of several Unix variants, networking with numerous technologies and vendors' equipment as well as scripting. We can discuss any other projects you have in mind. Contact me through the email address on the left or on my cell phone: (415) 608-6742.
