Professional Summary

Introduction:
I'm a Senior Software Engineer/Architect offering very strong software design and development experience. For about the past 14 years, my focus has been on designing and building applications based on www technologies ranging from C/Perl CGI through Java and SQL. This career branch was a natural outgrowth of prior experience with complex systems, computer networking technologies such as SNA and VTAM and building Computer-mediated Communications systems.

The unique value I provide in a project team is my very broad understanding of computer system architecture and my ability to quickly build a conceptual model which extends that understanding to the internals of specific technologies being used or considered for the project's implementation. My system perspective helps me identify components and features required to design and develop a complete solution which will meet business objectives.
