Services

Over the past 20 years, clients have used my services to design and build information systems in a variety of application areas, among them, insurance, flight scheduling, product sales and customer registration, and internet marketing.

Clients also like to use my deep knowledge of systems, especially in the areas of performance, scalability, and transactional systems, for special services. Examples of these special projects are the analysis of the performance of Borland's J2EE platform, and the design and implementation of an update-anywhere replicated database for Siemens.

In my 25-year software career, I have become proficient in a variety of platforms, languages, systems, and tools. But my recent development work has been based on the Java platform: Java for basic business logic, Spring, Hibernate, and Oracle for database access, Tomcat, Struts, JSP and Velocity for controller and view technologies, and JavaScript for browser-level control of web pages. I also draw on my network of seasoned software professionals to supplement my knowledge of specific tools and platforms.

But where you will find the most value in my services is in a depth of systems knowledge, an analytic problem solving sensibility, a passion for clean designs, and a hands-on approach to project leadership.

Work History

Clients include:

• MyBuys Inc., Redwood Shores, CA.
  Chief Architect of MyBuys' on-demand preference-based marketing application server. Technical lead of a team of 6 developers. Spearheaded the development of a web-based system for capturing consumer preferences, matching preferences to retailer inventories, and providing shopping alerts to consumers through email and RSS. Architected the system based on lightweight open-source Java technologies including Spring, Hibernate, Struts, and Velocity. Programmed significant parts of the system, including the base architectural infrastructure, and the server-side preference capture and preference matching functions.
• Borland Software Corporation, San Mateo, CA.
  Benchmarked the Borland Enterprise Server: Borland's J2EE platform. Implemented the TPC-W benchmark by using Java Servlets and EJBs. Deployed and tuned the benchmark on the Sun Solaris platform by using Oracle. Demonstrated a throughput of hundreds of web interactions per second, with sub-second average response time, for thousands of concurrent web users.
• Visigenic Software, Inc. [Later acquired by Borland], San Mateo, CA.
  Co-developed and supported the release of VisiChannel for ODBC, Visigenic's JDBC driver for ODBC.
• MarketFirst, Inc., Mountain View, CA.
  Produced COM and CORBA APIs to Marketfirst's core web-marketing services. Created a web-based user interface for authoring electronic marketing documents and surveys, by using Java Servlets, JSPs, and JavaScript.
• Siemens Information and Communication Networks, Santa Clara, CA.
  Consultant. Designed, implemented, and deployed an update-anywhere data replication scheme, based on the Sybase Replication Server, for the Siemens Modification Request Tracking System, a global software life cycle information system, with database replicas in California and Germany.
• Pacific A&M, San Bruno, CA.
  Led the development team of the Pacific A&M Information System, an insurance administration, marketing, and accounts receivable system. Designed, implemented, and deployed the system by using the INGRES RDBMS.
• Digital Equipment Corporation, Palo Alto, CA.
  Sybase on-site project lead for the symmetric multiprocessing port of the Sybase SQL Server to the DEC Alpha OSF/1 UNIX operating system. Led the porting effort. Developed execution analysis tools to identify and fix race conditions unique to the Alpha 64-bit SMP architecture. Analyzed the performance of the Sybase SQL Server on this platform by using TPC benchmarks.
• Sybase, Emeryville, CA.
  Client-site training instructor. Provided on-site training to Sybase customers throughout the US on core Sybase skills: concepts and facilities, application programming, system administration, and performance and tuning.
• Sun Microsystems, Milpitas, CA.
  Sybase instructor. Trained Sun's technical staff in the Sybase RDBMS.
