Senior DBA/Architect and Sybase SME

Work within database group to support application RDBMS’s and help DBA’s and Developers with SQL Performance and Tuning, Design techniques and how to use database products efficiently.

Extracted and reviewed critical legacy financial system data models in Power Designer.

Modified physical data models in structure and indexing to significantly improve performance by 3x to achieve SLA’s.

Performed data and systems migrations from Solaris and AIX to Redhat Linux. This involved custom ETL code and endian data migration to meet the production migration SLA’s. Migrations involved OLTP, OLAP and data replication components.

Stabilized several Sybase systems working to resolve application and vendor software bugs.

Designed security access models for Sybase IQ.

Designed Unix/Linux/SQL benchmark tools for Sybase ASE, Sybase IQ, SQL Server and Netezza.

Designed Sybase IQ/ASE benchmark, monitoring and alerting tools.

Designed Sybase IQ/ASE Designed global error handling templates.

Designed 6 level login security and audit for Sybase IQ, modeled in Visio using relational model

Tuned queries and significantly improved performance for multiple applications.

DBA for Sybase IQ and Sybase ASE using command line, shell scripts and Sybase Central.

DBA for SQL Server using SSMS, SSIS, SSRS, perfmon and profiler. Performed index and query tuning. Performed index defragmentation and data modeling using VISIO. Performed database backups and log transfers. Performed SQL Server upgrades and migrations.

DBA for Netezza using command line, shell scripts, NZADMIN, NZSQL, NZLOAD, NZUNLOAD, NZ_MIGRATE, NZ_GROOM, NZBACKUP and NZRESTORE.

Review of Netezza data distribution, space and zone maps. Review of business relational and dimensional models in Power Designer.

Due to the omission of corporate data management I had to build and separate 2 applications with conflicting source data rules that lost 3 months of development work due to the financials being reported incorrectly when data was loaded concurrently during QA testing.

Master data management was maintained manually for my projects where the corporate data was conformed by source. Definitions, domain, volume, volatility and cross reference were maintained in excel and reports were generated for reference by the application and data groups.
