Senior Pentaho ETL developer specializing in large-scale data migration.
What I'm looking for
I'm a Pentaho Data Integration professional with 9+ years working across ETL, data migration and data warehouse technologies. I have led a team of nine and driven significant production improvements across financial and analytics systems.
I designed and delivered reusable Pentaho ETL solutions, including metadata-injected pipelines and MS SQL to AWS Aurora Postgres migrations, and integrated ETL with Apache Kafka for publish/subscribe flows.
My contributions include shrinking an Oracle DB from 8 TB to 2 TB through archival and purging, reducing data load times by 25%, and improving query performance by 35% via complex SQL optimizations.
I work across Oracle, Postgres and MS SQL, automate scheduling migrations (AutoSys), and embrace cloud and scripting tools (AWS, Python) to produce reliable, high-volume ETL solutions that improve operational efficiency and client satisfaction.
