Professional Experience

Feb. 2001-present University of Illinois at Urbana-Champaign (UIUC)
Campus Information Technologies & Educational Services (CITES)
Technical Lead, Production Systems Group

Established and led a group of Unix administrators in a production data center environment using Solaris and AIX. Led effort to develop automation tools and configuration standardization to improve economy of scale. Was instrumental in the formation of separate groups to manage systems and services, which resulted in increased economy of scale, lower staff turnover, better system security, and higher quality of service for CITES's customers; presented a paper about this at LISA 2001 (see below). Designed and deployed a redundant storage system for UIUC's Student/Staff E-mail Cluster to improve reliability and reduce downtime. Redesigned and deployed a new architecture for routing inbound email at UIUC to improve scalability, fault tolerance, and efficiency.

Fall 1997-Feb. 2001 University of Illinois at Urbana-Champaign (UIUC)
Campus Information Technologies & Educational Services
Unix System Administrator, Workstation Services Group

Managed all aspects of Unix workstations and servers for campus customers, including hardware and software upgrades, software installation and configuration, and addition and deletion of user accounts. Presented training seminars on sendmail and Apache for campus Unix administrators.

Fall 1996-Spring 1998 University of Illinois at Urbana-Champaign (UIUC)
National Center for Supercomputing Applications (NCSA)
Unix System Administrator

Designed, implemented, and maintained network of HP and SGI workstations. Established backup procedures.

Summer 1997 Taos Mountain Consulting, Palo Alta, CA
