About Me

About Me

I am a 41-year-old full-stack developer with a huge enthusiasm to learn as much as possible in the shortest time possible. I derive great satisfaction from automating tasks — some might call it laziness, but I believe it's about finding better ways to spend your time than doing things manually.

My name is Christopher Rau, I'm a Senior Python/Django Developer from Denmark. I have been using Python and Django since 2013, and I must admit that I love what I'm currently doing with these awesome tools.

Over the years, I've worked in various industries, companies large and small, wearing multiple hats. My languages/weapons of choice are Python and JavaScript. Recently, I've expanded my skill set to iOS/macOS development using Swift (including SwiftUI and UIKit), leveraging Apple’s ecosystem and CloudKit for modern, scalable applications. Besides development, I enjoy building, tech writing, and content marketing.
