I'm a software engineer at heart.

I don't care very much what language you're code is written in - I've probably used it at some point. Besides, great software derives more from architecture than language features.

I do have some specialities, though.

App Maker

I submitted my first Android app to the launch Hackathon in 2009, and have been working with this platform ever since.

Network Engineer

I just love tinkering with secure, high-performance decentralized systems. Peer-to-peer or blockchain, that's my jam!

You need broad and deep experience? Let's join forces!


The goal is to build great products, and products need to bring joy. This simple logic applies whether the product is for personal enjoyment, or it is a tool for improving work life.

You cannot build this engaging quality without identifying and prioritizing customer needs, and designing your software to meet and exceed them.

Quality Assurance

But how do you know measure your success? By establishing processes that let you follow each feature from inception to the customer's hands and beyond.

As founder of a software QA company, I have helped clients achieve this countless times.


I am an entrepreneur at heart.

I have founded businesses before I held down my first permanent job. As you might expect, some of those failed...

A successful business isn't necessarily based on a novel idea, but it's always based on great execution - that's something I learned the hard way.


When you're struggling with limited resources, knowing where to invest effort now, and which tasks to postpone can make or break your startup.

Why make the same mistakes everyone else has made? Let's skip at least some, together!
