👋 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.

Go Patterns: Pipelines

by

Sometimes, when reviewing code, you come across a huge spaghetti of sadness. You’d love to refactor it, but it is just a list of steps that need to be executed in order.

Go Patterns: Elegant Parallel Queues

by

Processing items in a queue in parallel is one of the trickier subjects in programming. You don’t want to overload your systems, but you also want to maximize speed. Go has some unique tools to deal with it.
