Born in Wieliczka, Mąciwoda began playing bass guitar semi-professionally at the age of 15 with his father's encouragement.

His young age on the rock and roll circuit earned him the nickname "Baby", but within a few years Mąciwoda was touring Europe with a jazz fusion band called the Little Egoists, and for overlapping periods of time performed as a member of the avant-garde rock bands Düpą and Püdelsi, both based in Kraków.

[1] In 2009, he appeared on the WU-HAE's Opera Nowohucka album alongside such artists as Grzegorz Markowski, Maciej Maleńczuk and Olaf Deriglasoff.

[2] As of 2011, Mąciwoda has been collaborating with friend and fellow musician Efrem Wilder[3] in the outfit Stirwater.

After that the band broke up but the project Stirwater is continued as he is playing and recording with fellow musicians from all over the world e.g. Florian Hofer from Germany[4] or Atma Anur from UK.
