👋 Hi!

I’m a software engineer specializing in server applications and system-level software development, but sometimes I venture into the front end world too. Quite often I find myself taking a deep dive into a topic that tickles my brain.

When I’m not coding I like spending time outdoors, such as cycling, climbing. We are writing this blog together with my partner Sanja.

You can find most of my work on GitHub.

One Controller, One Action

by

How many actions do you put in a controller? 5-6? 20? What would you say if I told you my limit is just one method?

Building your own CDN for Fun and Profit

by

Fresh from the hold-my-beer department, why don’t we build our own little CDN? Oh, and it actually makes sense.

Docker 101: Linux Anatomy

by

Docker is (mostly) used to run Linux, but in order to successfully create a Docker image, we must first understand how Linux works.
