Jesper Christiansen

Hi, I'm Jesper. A software engineer currently living in the Bay Area, California. I'm from 🇩🇰 Denmark and moved to the US in 2013, where I currently live in the San Francisco Bay Area

The pronounciation of my name is closer to `yes-per`.

My current choice for building web apps would fall on Ruby on Rails and JavaScript/Typescript. I love writing code, not so much for the code itself - but more to solve real problems for people.

As a developer I find the things you can do with just a computer and text editor quite fascinating.
