About Sami

I'm a Finnish guy (he/him). My interests range from playing video games, watching video essays, finding my way in life to more sustainable ways of moving in a city.

I work in the government producing accessible ebooks. In my free time I'm a dog dad and the vice chair of the Helsinki pedestrians' association (in Finnish).

I believe doing precedes passion.

Smiling Sami.
