BI/ETL developer in mBank

Warsaw, Mazowieckie, Poland

About

For couple of years I’ve been working (and trying to fill the gap) between IT and business, mostly by creating reporting tools for managing staff. I know BI (Business Intelligence) software as well as wide range of DBs including most popular vendors. I’m familiar with full lifecycle of a project-from business requirements analysis to final release stage. I understand (and enjoy) specifics of working for multinational companies where different cultures, providers and needs meet.
