Professional Experience:
 
June 1997 to Present

Bull Worldwide Information Systems
13430 North Black Canyon Highway
Phoenix, Arizona 85029
Senior Software Engineer

Current assignment is providing the Dump and Debug solution to Bull High
Performance Computing platforms. This involves selecting Open Source Dump and
Debug products, wrapping them in customized scripts to provide advanced analysis
capability for compute node problems. and providing installation packaging and
usage documentation.  Also provided linux GUI applications to interact with the
dump/debug product to facilitate ease of configuration , dump analysis, and
obtaining technical support.

Previous  assignment was plugin developer for a Model-Driven Architecture
project using an open-source IDE (Eclipse) to facilitate the development and
deployment of J2EE Web service applications on Opensource Application Servers
(Jonas, Glassfish) from a modeling tool's XML export. The plugins are GUI-based
implementations that  parse the XML, build a metamodel, then process the
metamodel via Velocity engines to generate the Java classes and XML deployment
files to  complete the Webservice implementations via Spring injection. The
services are generated to use Hibernate or EJB3 as the database
Connection layer.
Also provided the capability to reverse-engineer a metamodel back into the
modeling tool. Wrote Junit tests to support the product.  

Previous assignment as project leader on re-design and integration of components
of Bull's operating system from the current mainframe environment to an Intel
64-bit PC platform under Linux utilizing  Virtual Interface methodology.
This has entailed implementation of shared-memory infrastructures under Windows
and Linux and socket implementations and the porting of the current Unix remote
applications, DSA and IPS, to Windows. Also involveds converting company
proprietary
operating system components from assembler language into C and C++ to achieve 
target performance levels. Built performance tools in Visual Basic to investigate
transfer
performance under this system.

Additionally, owned primary responsibility for embedded firmware that enables
direct
mainframe memory access for data to be passed to a scsi link for file transfer 
and E-commerce applications, replacing current outdated frontend network 
processors.

Other recent  assignment is  maintenance and  support of embedded software ( in
C) for ESCON (Enterprise Connectivity) firmware  for enhanced peripheral usage
and performance utilizing an Intel 960 processor chip. Developed graphical
interfaces in MS Visual Basic to process chip diagnostics for ESCON
troubleshooting analysis and to support current development of the 64-bit OS.
