2.00/5 (Submit Your Rating)

SUMMARY:

  • Leveraging 25 years of overall Data Warehousing, Business Intelligence, and ETL Development experience, I seek to empower companies in the fullest use of their most valuable asset, their business data. Working in various industries: Health Care, Chemical, Mortgage, Education, Manufacturing and most recently the Banking Industry, I continue to utilize years of experience obtained through new and exciting technologies, projects, and team collaborations and apply that knowledge effectively to allow companies to succeed in achieving their mission critical objectives and project initiatives on time and budget.
  • Extract Transform and Load (ETL) Technical Lead/Developer and Business Intelligence are my primary strengths as well as Database Architecture and Development but I firmly believe that communication and time management are of equal importance in achieving project success.
