For over 20 years, Mr. Kamfonas has been playing a leading role in designing and developing strategic systems for Fortune
100 businesses and government. From pioneering headline-makers, to lower profile decision support and back-office robust implementations
and integration projects, he repeatedly set architectural vision, designed highly functional solutions and mentored teams
in methods that pushed the envelope of common practice. He operated in diverse technology environments such as GE - Lockheed
Martin, SIAC/NYSE, Morgan Stanley, Freddie Mac, Ernst & Young, The Home Depot, and Food Lion. He combines extensive background
with practical experience in modeling and design of data-warehouses, VLDB, parallel and distributed architectures, as well
as software automation.
As chief architect for a large retailer for three years, he helped define and execute their
enterprise decision support architecture, including a multi-billion row data warehouse and marts. In a similar role at smaller
retailers he helped with performance enhancements and the deployment of an aggregation strategy. He has also been engaged
by SIAC to participate in the New Architecture Initiative (NAI) of the order processing systems of the NYSE, advising on database
technology selection and design around high performance reliable messaging infrastructure, as well as canonical message and
data administration standards development.
At a large investment bank, he led the modeling and server-side development of an operational store supporting the
daily P&L process for the controller organization, and participated in various strategic initiatives, including journal
history, position & balance warehouse renovation concept, provisioning architecture standard and tool evaluation, and
enterprise reporting.
He was the chief architect of the early Citibank Credit Card data warehouse, one of the largest multi-terabyte MPP implementations
of its time. Prior to this, in the early 90s, he led the architecture and part of the design of a $50MM cost management system
for GE-Aerospace (currently Lockheed Martin), the first design that implemented his Versioned Dimensional Model. Prior to
that he architected various systems in Lockheed Martin and GE Aerospace, including a cost management system, HR and benefits
systems and various logistic database systems.
He is currently president of InfoKarta Inc. investing in the development of large high performance quickly deployable analytical
databases. He served as Chief Architect and Director of Data Warehouse Technology for Lockheed Martin’s IS&T/NE.
He directed internal R&D, towards the deployment of model-driven high performance parallel data cleansing, transformation
and loading technology. He developed the Versioned Dimensional Model (VDM) for analytical databases, which address the temporal
correctness of historical dimensional databases and enhances conventional star-schema variants and methodologies. He has developed
techniques and algorithms for very large multi-level cubes with interactive response time and high availability, distinct
count capability, very large differential balance retention, and metadata-driven code generation.
