👋 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.

On the surface, Go doesn’t look like an object-oriented language. However, if we look deeper, OOP is not only possible, but an effective way to organize code.

Creating a fast website

What does it take to create a website that loads in under one second? Is the loading time the measure of speed?

If you’re reading this post, you’ve probably typed something like “should I quit social media” or similar expressions of the same thought into your favorite search engine. Don’t you worry, we’ll feed your confirmation bias right here.
