I’m a Canadian UX / Product designer currently living in Stockholm Sweden.


UX is a team effort, put simply, I can only do so much in my personal designer bubble.

Who is Stefan?

Hey! I’m Stefan Twerdochlib, a Canadian UX / Product Designer living in Sweden with my wife and 2 Cats (Yggdrasil and Jotunheir). Currently I work at H&M as Lead UX Designer, leading a team of designers on the checkout team and building a headless design system.

Create a hypothesis

I begin to understand problem we are trying to solve. By digging in to quantiative and qualitative analytics, to make sure we’re solving the right problem.


Define the Job to be done

It’s time to define. Each Job needs to tied to an outcome and set of KPIs (Key performace indicators). This ensures that we’re going to design for the expected outcomes.


Design for outcomes

NEVER designing in a vacuum! I make sure my team is with me every step of the way. From sketching, wireframing, UI to developer handoff testing at every stage always trying to disprove our hypothesis.


Deliver and iterate

Once launch is hit on the shinny red button, work is never done. One of my favorite parts. Watching analytics, and begin to optimize the design to meet our outcomes and hit the KPIs.
