Data Warehouse Architect
I am a data warehouse architect with expertise in the design, implementation, and maintenance of enterprise-scale business intelligence and data migration projects. I have led teams of people through every phase of Data Warehouse creation, and I can bring experience from high profile, large-scale clients such as NASA, the City and County of San Francisco, the US Air Force, and the US Postal Service. I have experience with the Capabilities and Maturities Model (CMM) development lifecycle standards, where I've learned processes for running organized, repeatable and successful data warehousing projects. I have personally designed data models, built ETL and reporting architecture, and administered databases and application servers.

Data Warehousing Experience:
Wright Patterson Air Force Base Dayton, OH, Data Warehouse Contractor (2003-Present)
- I am currently leading the Business Intelligence strategy for the Air Force ERP system. This includes architecting methods to bridge legacy system data and BI reporting with the new policies, procedures, and data introduced by the ERP. The design stretches from high level governance and policy issues to technical BI architecture and enterprise warehouse design.
- I performed as the technical team lead for a development team which integrated over 50 source systems and data marts into the data warehouse. Ultimately we were responsible for integrating maintenance, supply, logistics data, and systems tracking specific assets into the Air Force EDW.
- My team built standards and repeatable CMMI processes for every aspect of Data Warehouse management, including modeling and loading new source data, data mart processing, report specification and building, ongoing maintenance, and pretty much everything in between.
- My technical demands included Oracle, WebSphere MQ, Business Objects, Cognos, Informatica, and Teradata support, design, and development in a closely integrated environment.
FirstEnergy Corp. Akron, OH, Data Migration Contractor (2002-2003)
- Supplied technical expertise and programming support for a large scale SAP R/3 migration using Informatica, Oracle, and SAP/ABAP tools.
- Worked closely with both a functional and technical team to design, develop, test, and deploy a migration mechanism for Human Resources data.
US Postal Service Raleigh, NC, Data Warehouse Contractor (2002)
- Provide Informatica and data warehousing expertise for Postal's very large data warehouse initiative.
- Primary responsibility was on increasing performance on very large data loads to the warehouse. For example I reduced the running time for some loads from 80+ hours down to 4 hours.
Clients with KPMG Consulting Washington, DC, Senior Consultant (1998- 2002)
City and County of San Francisco (2000- 2001)
- Designed and implemented a terabyte scale data warehouse for the City.
- Responsible daily for Oracle tuning and DBA work, Informatica and Cognos design, development, and performance tuning. Also administered large NT and HP-UX servers.
- Marketed the warehouse to senior department heads, eventually creating departmental data marts and a distributed Oracle environment.
- Developed end user training, documentation, and robust testing/validation procedures.
National Aeronautics and Space Administration (NASA) (1999-2000)
- I was part of a team that designed and developed an enterprise-wide data warehouse (EDW) for NASA. I was the main technical resource on the project, and my duties included researching, specifying, purchasing and administering $1.5 million of Sun hardware running the Solaris operating system.
- I was involved in the entire lifecycle of this EDW. I met with scores of functional people from across the country to develop logical and physical data models. I led a small team in the Informatica development for data transformation and cleansing from disparate source systems to the Oracle EDW. We worked with the Holos OLAP package and Crystal Reports and Brio ad-hoc query tools to deliver a web-based reporting solution to the client's specifications.
Performance Executive (various clients)
- Performance Executive was a packaged data warehouse that we marketed to clients of our proprietary accounting systems. I was one of several technical resources on the project throughout my tenure at KPMG, and I was involved with every aspect of the product's creation, testing, and marketing. Primarily the product was back-ended in Oracle 7,8, or 8i, and Microsoft SQL Server, with an Informatica engine for data cleansing and transformation. The front-end tool of choice was Cognos Impromptu and PowerPlay, although some clients used Business Objects, Brio, Microstrategy and Crystal reports.
