Portland, OR, US

• Designed and implemented a sophisticated multi-node Nagios XI solution within a complex, highly secure environment.
• Converted check delivery from plaintext to TLS encrypted.
• Coordinated and oversaw the seamless collaboration among multiple stakeholders and technical teams to ensure successful implementation.

Designed, built, and manage two Nagios systems. One is for the subscriber LDAP systems (both wireline and wireless). Another is for the subscriber Cassandra system. Write wiki pages for each alert, so that on-call staff can click on an alert, and get more information about the alert. In short, create a monitoring system that makes as much sense as possible.

Lead monitoring engineer for two very large application environments: one, a replicated ODSEE LDAP environment, and the second, a Cassandra environment. Performed monitoring audits, conducted weekly monitoring requirements meetings, coding custom monitoring checks.

• System Performance analysis.
• Redesigned and rebuilt monitoring system using Nagios 3 and NetCool: Resulted in 90% less alerts and 10 times the accuracy of the previous system.
• DSEE 6.3 architecture and test environment deployment
