• Senior Data Grid Programmer; Programmer/Analyst IV, DICE(SRB/iRODS) team member, San Diego Supercomputer Center (returned September 2002 - present). Principal co-developer of IRODS; developed Database interface (ICAT), installation/testing systems, authentication, etc. Enhanced SRB/MCAT Administration Tool (Java). Extended SRB client/server protocol for new administration functions.

• Senior Software Engineer (Windows), Entropia, Inc. ( July 2000 - September 2002). Developed critical components of the Entropia Batch System (EBS). Ported a large Unix-based job scheduling system to Windows. Extended this for greater scalability, reliability, fault-tolerance. Developed the EBS PC client-host job manager (AppMom). Integrated the EBS AppMom with other Entropia infrastructure. Analyzed, debugged, and enhanced in this dynamic environment. [Was retained through all four layoffs during the period].

• Research Programmer/Analyst, Enablining Technologies, Data Intensive Appalications (1997-2000). Analysed/developed X.509 Certificate support software (Grid Security Infrastructure). Analyzed HPSS performance via transfer logs. Designed and developed HPSS Caching Discrete Event Simulation model. Designed and implemented the SDSC Encryption/Authentication (SEA) system. Designed and implemented Illustra and FTP drivers for the SDSC Storage Resource Broker. Evaluated NQE and other queuing systems for the DOCT testbed.

• Systems Software Special Projects (1994-1997). Designed and implemented a web-accessible computer hardware database (Illustra) for SDSC inventory management. Designed and implemented system software including: NSL UniTree 2.0 software (archival storage): Communications routines (RPC) to integrate new NameServer into NSL, NameServer transaction journalling and database reconstuction, Directory backup. Ported/developed Kerberos systems software for the Cray. Evaluated/ported/developed the Secure Shell for SDSC.

• Manager, Production Systems or Central Systems Software group (1988-1994). Responsible for systems software on CRAY C90, Y-MP, or X-MP, for periods, also Intel iPSC/860, nCUBE, and/or SCS-40.
