Professional Experience:

1989-Present, Senior Systems Programmer, Waisman Center, University of Wisconsin-Madison.

Network administrator and IT manager for a customer focused Waisman Computing Services IT group where uptime, quality of service and security are of prime importance. I currently manage network services delivered to over 700 client workstations in a health care research/provider environment on a cost recovery basis. Responsibilities include design, administration, security, operation, maintenance, and support of the network infrastructure, computing environment and related services for a research facility that is one of 14 national centers involved in human development and developmental disabilities with specialized clinical and outreach services.

Some of the more visible network services and activities I currently provide are:

• System management of a fault resilient, load balanced servers cluster implemented using HP's blade system that supplies network services to over 700 faculty, staff and students in a multi-disciplinary environment.
• Management of a shared multi-facility 8Gb/s dual fabric fiber channel SAN containing an EVA storage array with over 75 terabytes of storage.
• Checkpoint Firewall administration including inter-site VPN's and SmartDefense.
• Industrial strength PMDF internet messaging with custom virus checking, automatic updates and spam filtering using PreciseMail Anti-spam.
• Enterprise level file and print services using CIFS/Samba
• Secure web server configuration (Apache), updates and custom CGI scripts (C, DCL, PHP and PERL).
• LISTSERV mailing list configuration and maintenance.
• Other popular TCP/IP services such as DNS, POP, IMAP, FTP, SFTP, NFS, DHCP, SSH and TFTP.
• Install, configure and maintain associated hardware such as servers, storage, firewalls, switches, routers and UPS systems.
• Install, configure and support various commercial and open source server software packages.
• Day to day triage, troubleshooting and diagnosis of network and server related issues using RT ticketing system.
• Collect resource usage data to set rates for network services that will fully recover their cost.
• Establish baselines and analyze capacity to anticipate upgrades that will determine the future network infrastructure.

1982-1989, Data Systems Engineer, Plasma Fusion Center, Massachusetts Institute of Technology, Cambridge, MA. Responsible for the design, implementation and operation of the physics data acquisition subsystem for a large fusion energy research project known as the Tara Tandem Mirror. Served as a consultant to other staff engineers, scientists and contractors to integrate diagnostics into the data system and review designs of customized supporting hardware. Configured and managed a Vaxcluster system and a distributed Local Area network of clustered workstations used in related fusion experiments. Defined software architecture to catalog, archive and retrieve very large data sets to support analysis of physics data. Supervised staff application programmers and student workers. Maintained a VMS device driver and ACP, various commercial and public software packages. Configured and maintained a CAMAC (IEEE-583/595) optical serial highway in an adverse environment and developed diagnostic software to manage it's integrity.

1989, Independent Consultant, Applied Science and Technology, Woburn MA. Configured, installed and tested network infrastructure (wiring, hubs and bridges) to support a flexible 108 node Local Area Network (LAN) for a rapidly expanding high technology company.

1981-1982, Independent Consultant, part-time, Plasma Fusion Center, Massachusetts Institute of Technology, Cambridge, Massachusetts.
