    Played with electronic gadgets since childhood taking them apart and sometimes managing to put them back together again. Can deal with a bunch of common/popular programming languages but prefers Python if other design considerations are not forcing their hand. Often seen representing hacklab.fi at various events.Github: rambo LinkedIn: eeroafheurlin
