Senior Consultant: Apr. 98 to Mar. 99 (1 year)
Consultant to Geico Direct, Bethesda, MD on behalf of Internet Information Services, Inc. of Bethesda, MD
Analyzed, architected, bid, and won a large multi-developer contract to build a flexible, maintainable N-tier web interface to Geico's mainframe and OS/2 based quoting system.  The environment involves building a large and very complicated system in a short amount of time with analysis that is incomplete or unavailable until just before the delivery date.  Due to the nature of the regulated insurance industry, changes are required to the system very frequently and often must occur on specific dates automatically.

Due to the environment and complexity of the business rules the architecture utilizes a rule based processing engine embedded in a web targeted transaction monitor system (Netscape Application Server, NAS).  The system allows specification of applications almost completely via meta-data and business rules.  The system also involves Netscape Enterprise Server, Neuron Data's Elements Advisor (a Java based rule engine suite), and Oracle 8 running on Solaris servers. This system has become very successful.

In early phases of the project, I acted as customer liaison, project manager (including personnel, budget, schedule, and proposal), developer and project-manager interviewer, technical lead, architect lead, system administrator, and designer.  After staffing was completed, I concentrated on the lead architect role to complete the design details and development with the other developers.  I participated in developer and customer education sessions on the rule and meta-data concepts and technologies involved, helped solve development problems, and contributed to schedule evolution.

The design of this system is a cutting edge and optimum solution to the problem of rapidly building and maintaining a wide range of business applications, especially web based N-tier servers.  There are no commercial or literature examples of a similar combination of object oriented, transaction processing, rule based and meta-data driven application environments predating this project.

Lead and managed technical staff of 7 in the early phase of the project until a dedicated project manager could be brought.
