How to become a developer/commiter to FreeBSD

Thu Dec 1 12:40:53 UTC 2016

Hi, I'm a developer, working in my own (one person) company.  I live in Poland and work for USA for 4,5 years already.  I've started working as developer in 2006 in local companies in Poland.   I know C, C++, Python, Ruby, Ruby on Rails, SQL, and many more computer languages.   I want to contribute to FreeBSD in my spare time, but not sure who should I contact.  I'm using FreeBSD since about 2000-2001.   Best Regards.
