Regidor Teng
@regidorteng
Oracle PL/SQL Developer specializing in retail and healthcare systems modernization and production support.
United StatesWhat I'm looking for
I’m an Oracle PL/SQL Developer with extensive systems development and maintenance experience across Health Management Organizations (HMOs), life insurance, medical clinic management, and retail management systems. I’ve spent my career designing, coding, testing, and maintaining database objects and PL/SQL components that power critical business workflows.
At MAPSYS, Inc., I’m assigned to Abercrombie and Fitch with the EMPS Team, researching and documenting the current Retail Management System (RMS) ahead of the conversion to Oracle Retail Merchandising Foundation Cloud Services (MFCS). I code, test, and tune new and existing PL/SQL packages, along with related tables and objects to support the MFCS implementation.
Previously, I supported production operations by monitoring job runs and coordinating resolution of incidents at CareFirst BlueCross BlueShield. I’ve also delivered PL/SQL and SQL development for manufacturing systems (Oracle Forms and Reports 10g) and JPMorgan Chase Bank’s risk assessment data warehouse workflows, including SQL, SQL*Loader, and PL/SQL into staging tables.
