Southwest Florida Water Management District
Tampa, FL
Senior Data Warehouse Consultant
  • Assumed responsibility for a mission critical Operational Data Store (ODS) for the Water Information Management System (WMIS). Reverse engineered source code for all database objects and programs and placed them under source code control in MS Team Foundation Server. Implemented scripted database deployment/build process for the ODS. Implemented branching and merging for the ODS code. Rewrote the ETL process to include enhanced process and error logging while optimizing performance and reliability. Implemented an incremental update strategy using code generated Oracle MERGE commands. Documented the process and organization of data and code for follow on developers.
