From 1998 to 2016 I’ve been working in Łódź Voivodeship Office, in Citizenship and Foreigners Department. From 2009 to January 2016 I was the head of the department. During that time I was also voivode’s proxy in the matters of national and ethnical minorities. As a leader of almost 90-person team I was responsible for executing migration policy in Łódź Voivodeship, supervising passport and citizenship tasks.

I’ve been a nominated civil service worker since 2006.

During my years of work in government administration on voivodeship level I’ve received many awards and distinctions including: medal for my services to the police, medal for my services to the border guard, medal for my services to the defense of Poland. 

I’m a graduate of Cardinal Wyszyński University in Warsaw.
