Designed and built a series of highly available stacks in support of UC Merced's identity management replacement project, utilizing micro-services and the AWS Well-Architected Framework. The stack made use of Cloudformation templates to create a number of resources in AWS, including VPC components, RDS instances, Lambda functions, EC2 Autoscaling groups, ECS Clusters, Route53 records, and Application Load Balancers.

Heavy emphasis on RedHat/CentOS Linux systems in a VMWare ESX environment.  Deployed and maintained servers, switches, routers, load-balancers, firewalls, and monitoring. Served as mentor for junior systems administrators.Major Accomplishments:1. Redesigned and simplified the OIST network architecture in preparation for move to new data center during Campus Data Center renovation. Migrated from legacy Foundry router to x86 Linux OSPF router using the Quagga routing suite, saving roughly $50K over the next 5 years on routing hardware support costs.2. Deployed Xythos Enterprise Content Management System intended for use as a campus wide document management system. Utilized Xythos to distribute mainframe print jobs as PDF's to end users, thereby saving $200K on annual hardware maintenance and staffing costs for physical print delivery. 3. Deployed a new IBM Tivoli Storage Manager Enterprise Backup system used for Administrative Computing and Application Developer backup and disaster recovery. 4. Deployed prototype Disaster Recovery / Business Continuity VMWare cluster at San Diego Supercomputer Center.5. Designed and implemented a monitoring, signaling, and command and control system for power and temperature/humidity events in North Hall Data Center. Show less

Provided authentication/authorization, web-hosting, e-mail, and file storage services for departmental personnel and remote collaborators.  Maintained Linux server nodes across a nation-wide grid (BIRN) for the storage and collaborative sharing of NIH-funded research data.  Responsible for administration and backup of large scale data storage servers (Twelve Sun X4500's with 24-48 TB each of raw storage capacity) for storage of 3D microscopy imaging data at the National Center for Microscopy and Imaging Research (NCMIR).Major Accomplishments:1. Researched, tested, and performed upgrade of departmental document management system (Xerox Docushare) to current version (7.0) from a version that was already several years out of date (3.5), and for which no supported upgrade path existed.2. Deployed and maintained Solaris Jumpstart server for unattended installation and management of Solaris OS and ZFS pools/volumes on Sun X4500 storage servers.3. Streamlined Rocks Linux Distribution and built RPM's for BIRN software packages in an attempt to create a VMWare appliance of BIRN software that fit on a DVD, called 'BIRN on a Disk'.4. Mapped out NCMIR server infrastructure, and consolidated, relocated, and sometimes required creative measures to protect servers during server room renovation. Show less
