At DXC Technology Poland (Luxoft), I build and support a large-scale financial data platform for MUFG Bank EMEA, integrating external data sources for regulatory and internal reporting. I've developed and maintained 150+ ETL workflows, optimized 700+ SQL queries, and reduced batch execution time by 20%.
Previously at IBA-Group, I designed and implemented 300+ ETL processes for an IBM financial data platform supporting enterprise data warehouse reporting and analytics. I also delivered 700+ unit tests, 400+ technical documents, and a monitoring application for ETL execution status.
Across 7+ years, I've worked end to end—from requirements and technical design through testing, deployment, production support, data validation, and issue resolution.
