Łukasz - well known in the community under the nickname @bragi - has made many contributions to the Ruby community over the years. He loved programming and his influence on shaping the Polish Ruby on Rails scene as it is today is immeasurable. He was a respected leader, mentor, developer and entrepreneur - an owner of one of the largest Ruby on Rails company in Poland - Ragnarson and a founder of Shelly Cloud.
He will be dearly missed.
We are sending our sincere condolences to his family, friends & community.
