Principal Software Engineer 6/2015 - 9/2017Designed and implemented a sequence of C and C++ multi-threaded Linux/Solaris processes to enable the ACSLS library control server to control the new Oracle-STK SL4000 automated tape library via an HTTPS/SOAP (gSOAP) interface. A focal point of this design was to maximize parallel processing and concurrency.Principal Software Engineer 6/2016 - 7/2016Designed and implemented the HW monitor interface, to the “feature card” processor within an SL4000 library, as an HTTP Web Client using gSOAP.Principal Software Engineer 4/2014 - 8/2014Updated the existing monitor and control interface, to a physical robotic device within an SL4000 library, as a multi-threaded HTTP Web Service/Client using gSOAP.Principal Software Engineer 6/2013 - 6/2015Designed and Implemented a SCSI Media Changer device over Fibre Channel physical interface for the new SL4000 tape library. Components of the solution stack included: a Linux kernel driver for the Qlogic QL 25xx chip, a multi-threaded user-space app to relay SCSI CDB’s to/from a WebService in WebLogic, and the associated SCSI CDB handler application running within WebLogic.Principal Software Engineer 5/2012 - 6/2013Designed and implemented a prototype RESTful Web Service using Java EE 5, Jdeveloper, WebLogic, Jersey and JAXB on the new Oracle-STK SL4000 automated tape library.Principal Software Engineer 2/2012 - 5/2012Designed and implemented a C multi-threaded ACSAPI client that enabled the Oracle LTFS SW application to control Oracle-STK tape libraries via an ACSLS library control server.Principal Software Engineer 11/2011 - 1/2012System level Certification testing of Oracle-STK tape-library and tape-drive products with the current OS releases and HW from IBM on their iSeries (AS/400) platforms.

Senior Software Engineer 4/2004 - 6/2005Created design specifications, using UML methodologies, for tape drive emulation in a Virtual Tape Library storage appliance. Addl. responsibilities included virtual tape drive analysis team lead.Senior Software Engineer 4/2002 - 4/2004Designed and implemented the iSCSI subsystem and related iSCSI Windows client for a journaling software application written in Java and C on a Linux platform. Senior Software Engineer 9/2001 - 3/2002Designed and implemented changes to the client-side API of a robotic tape library client/server control application. This API is distributed as a Unix C Software Development toolKit.Senior Software Engineer 6/2000 - 9/2001Designed and implemented an HTTP/XML servlet based client interface to a robotic tape library control application using Java and C on a Linux platform.Senior Software Engineer 6/1999 - 6/2000Designed and implemented changes for an iterative release of a main-frame based robotic tape library control application. These changes enabled the application to share an ESCON/FICON attached VSM amongst various other main-frame hosts.Senior Software Engineer 1/1998 - 6/1999Designed and implemented error recovery code in a component of a main-frame based virtual tape storage device. This software was implemented using C++ in an OpenEdition address space on an IBM System 390 platform.Senior Software Engineer 1/1997 - 12/1997Designed and implemented the Berkeley sockets interface in 370 assembler from a main-frame based tape library control application to a network attached tape library management unit.Staff Software Engineer 6/95 - 12/96Designed and implemented changes for an iterative release of a main-frame based robotic tape library control application using C and 370 assembler.Software Engineer 6/91 - 6/95Designed and implemented an IBM AS/400 C client application to enable connectivity to StorageTek automated tape libraries and tape devices.
