What I'm looking for

I’m looking for a challenging Oracle PL/SQL Developer role where I can leverage 6+ years in SQL/PLSQL, ETL, and performance tuning to build scalable database solutions, improve efficiency, and deliver reliable production outcomes.

I’m an Oracle PL/SQL Developer and Production Support Engineer with 6+ years of experience in SQL, PL/SQL development, ETL, and data warehousing. I specialize in designing and delivering robust database objects—stored procedures, functions, packages, triggers, views, indexes, sequences, and synonyms—to meet complex business requirements.

I’m hands-on with performance tuning and query optimization using execution plans, indexing strategies, and advanced PL/SQL techniques like Bulk Collect and FORALL to efficiently process large volumes of data. I also manage end-to-end ETL workflows—data extraction, transformation, and loading—using SQL*Loader and PL/SQL to ensure data accuracy and integrity across systems.

In production, I take ownership of troubleshooting, debugging, and incident resolution while meeting SLA-driven support expectations. I perform incident analysis and Root Cause Analysis (RCA), execute impact analysis for change requests, validate database objects post-deployment, and use automated SQL and UNIX shell scripting for monitoring and batch job validation—continuously improving system stability and performance in Agile/Scrum environments.
