Message

At BAWAG P.S.K., I architected the in-house replacement of a vendor platform for central-bank regulatory reporting. I designed the staging and reporting-cube models and Airflow pipelines loading Oracle data into PostgreSQL, with two phases in production.

I’ve also designed data platforms across banking, fintech, government, and telecom, and led and mentored teams of data engineers. In my independent projects, I built a code lineage engine for Python, Airflow, and PL/SQL, and an iOS-first loyalty and CRM platform.
