Joseph S. Barrera III
I am currently a Senior Software Engineer in the Google Groups project, working to move Groups to newer software infrastructure.
From 2012 through May 2013 I was a Software Developer (Research) for the Linac Coherent Light Source (LCLS) at Stanford Linear Accelerator (SLAC). I worked on the data acquisition and analysis software (C++ and Python).
From 2005 through 2011 I was a Senior Software Architect at IBM working on the Tivoli Application Dependency Discovery Manager (TADDM), concentrating on the Windows Discovery and Enterprise CMDB components. Before IBM, I was at Collation, a startup acquired by IBM for the technology now in use by TADDM.
Before IBM and Collation, I was a Senior Software Engineer at CenterRun (which was acquired by Sun), working on Microsoft-specific portions of the CenterRun product, a tool to automate the configuration and deployment of applications across the enterprise. Before CenterRun, I spent five months as a contractor at Nuasis, greatly improving reliability and performance of the email server (IMAP and SMTP) at the core of their call center product.
For three years I was a Software Architect at KANA, working on performance and scalability issues. In particular, I developed a clustered version of the KANA Marketing product, and I optimized database usage in its job scheduler to improve performance. I actually started at Rubric, where KMA was originally developed; Rubric was acquired by Broadbase, and it in turn merged with Kana.
Before KANA, I spent seven years in Microsoft Research. For three years, I was a member of the Bay Area Reseach Center (BARC) in Microsoft Research. I worked with Jim Gray and the other members of BARC Scalable Servers group. I helped add support for MS Cluster Server to SQL Server 6.5 and 7.0. I was an early alpha/beta tester for Microsoft Cluster Server, and designed and gave demos and tutorials of MSCS.
Before joining BARC, I worked on the Rialto and Tiger projects. Rialto was a small, real-time, COM-centered operating system for consumer devices, and was used in Microsoft's ITV trial with NTT in Yokosuka, Japan. (The processor scheduler work I did in Rialto also made its way into MMLite, an embedded operating system.) Tiger was a PC-cluster-based video server that later shipped as Microsoft NetShow Theater Server.
Before Microsoft, I was a graduate student in the School of Computer Science at Carnegie Mellon University (M.S. 1990). I was a member of the Mach operating system project, headed by Richard F. Rashid. Rick, I, and several others left Mach and CMU to join Microsoft around 1992; many of us joined what is now the Systems and Networking Research Group in Microsoft Research. In my last years at Carnegie Mellon, I consulted for Cray Research and Intel on operating system support for their MPP products, as well as for the Open Software Foundation Research Institute (now Open Group Advanced Research). My B.S. in Computer Science is from Harvey Mudd (1986), as one of Mike Erlinger's first students.
