I am always seeking ways to learn and perfect my skills and I was able to do that with Oracle. I rubbed shoulders with developers consulting on database design, SQL Performance and Tuning. I tracked database and I/O activity for the business programs and advised decision makers on specific performance improvements for indexes and SQL access. Some key achievements I had while here:• Used Rapid Install and environment cloning with Rapid Clone to expedite efficiency with Oracle Applications R11/R12 configurations. • Identified infrastructure deficiencies through log and trace file monitoring and applied O/S patches minimizing any defects.

After almost ten years as a Database Administrator specializing in Oracle databases I took this position with PeopleSoft for a new challenge. I collaborated daily with developers and quality assurance to identify specific database deficits and developed appropriate recovery and security strategies. I was able to configure Oracle / DB2 / SQL 2000 databases while issuing technical expertise for the PeopleSoft Enterprise environment.
