PROFESSIONAL EXPERIENCE:

Sr. Business Intelligence Developer, Data Warehouse Architect

Confidential, Portland, OR

  • Remodel develop existing processes to be cohesive to a new architectural strategy.
  • Design, model and develop ETL data flows from multiple source systems through the data warehouse to various data marts.
  • Ensure data integrity and continuity across multiple systems
  • Work closely with third party vendors designing, developing and testing data exchanges.
  • Work with end users to gather project requirements, define metrics, establish development roadmaps and make the appropriate design recommendations.
  • Provide after-hours support for critical systems and data flows.
  • Design and develop frameworks to enhance data warehouse performance and utilization.
  • Ensure adherence to standards and best practices.
  • Streamlined overall data warehouse design by consolidating multiple staging and warehouse databases into single database instances. This decreased the complexity of the environment by magnitudes, reduced the amount of data redundancy, reduced the number of break points, increased performance, increased stability and made the entire environment easier to support.
  • Remodeled data flows from a primary data source to a third-party vendor to increase data stability. This was over a year-long effort with multiple interim releases.
  • Remodeledfsf all dimension and fact ETL data flows and objects to adhere to revised architectural standards.
  • Designed, modeled and implemented from scratch the MicroStrategy reporting data mart with over 400 database objects in the initial deployment.
  • Converted unsupportable SSIS package logic to stored procedure calls within individual tasks. This greatly reduced the amount of time spent troubleshooting data quality issues and increased overall performance of the packages.
  • Designed and developed a data publication framework for quickly and easily moving data across different databases and database servers.
  • Introduced partitioning methodologies not previously used in the data warehouse environment. I also wrote a small suite of utility procedures that could be used within calling procedures to help facilitate partition functionality.
  • Introduced the use of metadata to control process behaviors as opposed to business rules being imbedded or hard-coded within source code.
  • SQL Server upgrade project. This affected all data warehouse, warehouse management, SAGE, COGNOS, Logility and MicroStrategy databases
