David G. Lewis is a technology consultant in the Washington D.C. area, specializing in enterprise software development and technology management. He has been active in the design, development, and management of distributed object-oriented technology for more than 10 years. David began his career working on an object-oriented point-of-sale system in C on a DEC Rainbow running Venix in 1986. The company failed, but the product's successful use of object-oriented principles, reusable frameworks, and thoughtful design demonstrated the merits of this approach. Thus began a career-long commitment to object-oriented design and software reuse.

David's contributions in this area included a persistence framework for the GenBank project at Los Alamos National Laboratory; file-system technology licensed for the NeXTSTEP operating system; and key roles in the development of object-oriented systems, reusable frameworks, and technology adoption at Washington-area companies including Fannie Mae, MCI, and T. Rowe Price. He is currently involved in developing and promoting CORBA technology at a start-up company in northern Virginia. David graduated from the Great Books Program at St. John's College in Santa Fe in 1985.
