During this short period, I was developing and optimizing an Oracle-based account and debt management system at EOS.

Working as part of the BI/DWH team, I was developing the power plant information systems of E.ON and MAVIR (Hungarian Transmission System Operator) - mostly the ODS interfaces with the satellite systems and the ETL / Data Quality processes to cleanse, aggregate and populate measurement data to the Datawarehouse. Later on, I was involved in the development of the reporting layer - including materialized view optimization, OBIEE 10g / 11g report and dashboard development, scorecard management.
