            Software Engineer, consulting Jul 1994 - Dec 1995, 
                               full-time Dec 1995 - May 1996.

* Designed, coded and deployed initial Industry.Net web-site in Aug 1994
  using Perl5 and NCSA httpd.
* Designed Oracle database schemas to store catalogs and integrated into
  CGI programs using ProC and Oraperl.
* Customized two httpd servers (NCSA and plexus) to embed Oraperl and
  persistent processes to obtain better Web response-time.
* Developed initial commerce system at Industry.Net using Oraperl based
  upon consultation with business clients.  Designed product-data storage
  schemas to reflect business practices.
* Designed a flexible attribute-value based object storage schema in
  Oracle for storing heterogeneous business information.
* Designed and implemented a light-weight, high-performance logging
  system based upon UDP packets and a multi-threaded buffering system
  using shared memory and semaphores.
* Designed and implemented under contract to NIST/MEP a forum for
  anonymous, secure negotiations based upon Notes/Domino using Lotus
  Script and Notes agents.  Also designed new cryptographic protocols for
  triple-blind negotiations.
* Designed and implemented a generalized templating system for
  displaying arbitrary legacy data in diverse output formats. 
* Headed a project team that developed a prototype system for automated
  scanning, OCRing, indexing and Web-publishing of bulk paper-documents.
  Used Adobe Capture, ftp, Excite text-search engine, Perl and cron.
* Designed and implemented a high-speed user-interface in multi-threaded
  Java, FastCGI and Oraperl to permit untrained temps to search
  Industry.Net's database of 300,000 companies.  Achieved 100ms
  response-time, permitting incremental querying of the database upon each
  keystroke by the user.
* Participated in the design of a high-performance commerce architecture
  based upon messaging middleware.
