June, 2005 to present; Sungard Higher Education
Director, Advanced Concepts. I lead a group that is responsible for innovating the company's business through technology. In particular, we look at higher education business problems, research solutions, provide vision and produce proof of concepts for possible future products and services. Our current projects include work in composite applications, SOA and rich internet applications.
Technology Strategy Architect. As a member of the CTO's Technology Strategy Group, I am responsible for developing technology strategy for Middleware and user interface technologies to be used in the company's higher education products. I work with customers, product management, product development and technology vendors.
September, 1999 to December 2004: teaching, writing and consulting
Senior Enterprise Architect. In cooperation with jGuru and The Middleware Company, I have been writing, teaching and consulting about J2EE and distributed object technologies. I created The Middleware Company's popular Architect's Course and has given it to several hundred enterprise architects. The reviews of this course have been outstanding.
September, 1996 to September, 1999: Borland Corporation, San Mateo, CA.
Product Architect. I lead an effort to design and implement a tool and framework for rapidly constructing distributed applications out of CORBA components, implemented in Java. I did the majority of the design and implementation of the product. The product became known as the VisiBroker Application Partitioner for Java. The product was in beta testing when Borland acquired Visigenic Software. At Borland, I was an architect of Borland's first (pre J2EE) CORBA-based application server product and made a significant contribution to the implementation of it.
September, 1991 to September, 1996: Sun Microsystems, Mountain View, California
Senior Staff Engineer. At SunSoft, I was instrumental in the definition and architecture of NEO, SunSoft’s OMG CORBA-based distributed object product. I defined the distributed application model for NEO and lead a group in the implementation of it. Previously I was the architect of the Object Services in the NEO product. The service specifications were accepted as part of the OMG’s CORBA Object Services (COSS) standards. I am the principal author of five COSS standards.
July, 1988 to August, 1991: Hewlett-Packard Laboratories, Palo Alto, California
Researcher. I performed research in distributed object systems to support distributed applications. I participated in the design and implementation of the Common Services distributed C++ object system. I advised HP product divisions that are producing HP’s distributed New Wave computing. I worked on concurrency models for distributed and cooperative applications. I wrote several papers on distributed object systems, long-lived transactions and interfaces in C++. I organized a workshop on transactions and objects at the 1990 OOPSLA conference.
September 1983 to June, 1988: University of California, San Diego
Research Assistant. I was supported by the Computer Systems Research Group at UC San Diego, doing research in distributed systems. I designed, implemented and managed a team of students in two distributed systems projects: a parallel procedure call system and a replicated, distributed file system for UNIX. This work resulted in several papers and invited presentations.
Instructor. I taught four upper division courses in the UC San Diego Computer Science Department.
February, 1981 to April, 1983: Amdahl Corporation, Sunnyvale, California.
Software Engineer. I participated in the design, implementation, maintenance and training phases of a product to help programmers maintain software. I designed a week long course and video training material for the product. I presented a paper related to the product at the 6th IEEE International Software Engineering Conference in Tokyo, Japan.

TORPEDO
I created The Testbed of Object-Relational Products for Enterprise Distributed Objects (TORPEDO). TORPEDO is designed to reveal the sophistication of Object-Relational mapping software in accessing databases in single server and clustered environments. TORPEDO defines a set of realistic application-level operations that detect a significant set of database access optimizations. TORPEDO supports different Java APIs for O-R mapping including Container Managed Persistence (CMP 2.x), Java Data Objects (JDO), Oracle TopLink, and Hibernate. More information on TORPEDO is available at www.middlewareRESEARCH.com/torpedo and a paper about TORPEDO is to appear at the 21st IEEE International Conference on Data Engineering in Tokyo.
Xbeans
I lead an open-source project to create a repository of Xbeans. Xbeans are Java Beans that process XML and can be easily composed into distributed data flow applications. More information about the project is available at www.xbeans.org. The project has produced two releases and has been downloaded by several thousand people. I have spoken about the project at numerous industrial and academic conferences.
Application Partitioner for Java, Inprise Application Server
I lead an effort to design and implement a tool and framework for rapidly constructing distributed applications out of CORBA components, implemented in Java. I did the majority of the design and implementation of the product. The tool and framework allow application designers to graphically partition and connect Java components into distributed applications. The product provides a novel and flexible binding and instantiation model for distributed application components.
Object Services
I was the architect for a group designing and implementing distributed Object Services for relationships, events, externalization, object life cycle, naming and object properties. The services are a key component of SunSoft’s NEO family of products. The services have been standardized by the Object Management Group (OMG) as the COSS standard. I am the principle author of six of the COSS standards.
CommonServices
I participated in the design and implementation of the CommonServices system at HP Laboratories. My principle contribution was the design and implementation of the interface definition language, compiler and run-time library. The system provides a C++ programming model of distributed objects. Application programmers simply write distributed, object-oriented applications as CommonServices interfaces and C++ class implementations. The system was the basis of HP’s submission to the Object Management Group’s (OMG) CORBA standard.
PARPC
I designed, implemented and supported the PARPC system at the University of California, San Diego. The PARPC system adds parallel remote procedure calls to C and C++ programs. Parallel remote procedure calls are useful in a distributed environment for multi-cast communication, replication and remote procedure calls. PARPC supports a high-level network process model. The system is available on a variety of platforms and has been given to several universities and research institutions.
Gemini file system
I participated in the design and implementation of the Gemini file system at the University of California, San Diego. The Gemini file system is a UNIX compatible replicated file system. It was used as a test-bed for experimenting with file replication policies.
