Hello, 👋, my name is Sophia Brandt.

I’m a tax officer and polyglot programmer.

I love functional programming (Elixir, Reason), React.js, Go, Vim, DevOps with Docker, mobile app development with Flutter, data-science and machine-learning, pen & paper role-playing games, and writing.

I volunteer as a Star Mentor and GitHub team member to the Zero to Mastery community where I help and support fledgling programmers.

I’m interested in conflict resolution and trained as a mediator at Fernuniversität Hagen.


All my coding-related writing is available on https://www.rockyourcode.com.

You can find selected articles on Dev.to as well.
