Joe Karlsson is a software engineer and Developer Advocate at MongoDB. He comes from the frozen tundra known as Minneapolis, Minnesota (and yes, it does get really cold here, and no, not everyone here has the accent from the movie, Fargo 😝). He has been primarily a Node and JavaScript engineer, but he also really enjoy the “math-y” parts about coding. He has been writing, teaching, and talking about code his entire career.

He is the co-creator of open source software, including bechdel.io which tells you if a movie script passes the Bechdel Test or not. In his free time, he is usually drinking Gin and Tonics, eating at a new restaurant, or working on an art project (his medium is a 3D printer and an Arduino).
