Hey, I'm Viktor
Head of Engineering at Babbel.
Founder at Rather, Activities Matter and Colloquies.
Bias for action, driven by purpose
As a Tech Lead for Babbel's 2024 rebrand I led the tech work of 300+ people. I've managed 5 teams and shipped many impactful features across a decade in tech.
By bringing engineering, managmenet and AI expertise to the table I excell at building teams and environments where people are willing and able to innovate.
My apps, Rather, Activities Matter and Colloquies, have no retention or revenue pressure. They just solve actual real problems with human-centered design.

Beyond the code
Life outside work
Reading
Books are how I stay curious. I'm drawn to systems thinking, behavioral science, and the occasional novel that challenges how I see the world. A good book can reshape how I approach both leadership and life.
Triathlon
There's something clarifying about training for three disciplines at once. It teaches patience, forces recovery, and reminds me that progress isn't always linear. The race is just the celebration — the work happens in the dark mornings.
Cooking
Cooking is my creative reset. No screens, no meetings — just ingredients, timing, and the satisfaction of feeding people I care about. It's meditative in a way that nothing else quite matches.
Featured work
From leading engineering teams to building side projects that solve real problems.

Sequencing Is Not an Opinion
Priority orders work by what we want. Sequencing orders it by what has to be true first. Overrule the second as a habit and the bill lands on the people first.

Pushes, Bearings and Mass
Everyone wants a flywheel. A real one has three parts, and every hour you spend goes into one of them. Most weeks are correctly mostly pushes. The mistake is calling a push an investment.
