    TIER hired me in 2018 to design, prototype, and document their first in-house app.

    I built multiple complex prototypes and worked with the founders to perfect the user experience.

    We mixed periods of focused work, short check-ins, and longer deep dives. That yielded best results.

    The extendable design system we built and documented made it easy for future teams to pick up where we left off.

    The apps launched about 4 months after we finished. The iOS version hit #1 in Germany one day after launching.

    Doodle hired me in 2016 to improve their native apps designed for frequent users.

    We’d deliver everything the website had, but better. We’d make it the best version of Doodle.

    We ran extensive user interviews and usability testing. Designed an iMessage app. Increased poll creation by 30 %. Launched a full visual redesign. Lifted ratings from ~4.0 to 4.6–4.8 out of 5 stars.

    Our incremental process was very rewarding. I had such a great time working with all the talented people at Doodle.

    Designed, user tested, and launched the first native apps for the SoftBank-backed unicorn travel startup. Drove customer retention by designing an in-app ticket feature. Collaborated on a cross-platform design style guide.

    GetYourGuide lets you book tours and activities. I was hired to design native apps to accompany their website.

    I assisted the launch of both apps, and later worked on adding new features and refining existing ones.

    User testing in particular was a huge part of all our efforts. I learned a lot working with the experienced team at GetYourGuide.

  • “Probably the best team mate I've ever had as a product designer. He documents everything. It’s easy for anyone to pick up where he left off — a great asset for a freelancer.

    He’ll plan his day upfront, tune out every distraction, and won’t waste time doing trivial tasks. He doesn’t waste your money.

    He's very diplomatic, approachable, respectful, authentic, and has a good sense of humour. I sensed most of these qualities the first day we met and he hasn't changed since. We ended up becoming friends.

    And just to wrap up... he’s very open minded, eager to learn, and open for feedback. All important traits to have as a colleague.”

  • “Andy is the best designer I have worked with.

    He doesn’t only deliver excellent works but also cares about the development of his fellow colleagues.

    When I started working with Andy, I was just starting my career as a product designer. He mentored me by sharing his knowledge in design tools, user research methodology, design system, and more. He even gave me some coding lessons!

    What I've learned from him helped me to become a designer I am today and I am so glad I met Andy at one of my very first design jobs!”

How’s your day going so far? I hope everything’s great. If it’s not, I hope it does get better soon.

Did you eat breakfast today? It’s supposed to be an important meal. I probably had a piece of toast with vegan spread on it, and a fried egg. I almost always have that. It’s nothing special and I usually get pretty hungry before noon. Then I have to pester people around me to come eat lunch early. They think I’m crazy.

Earth seen from space

We’re on a rock in space

You’re reading this message using your eyeballs, which evolved over millions of years. Think about that. Pretty amazing, right?

We haven’t yet found anything like us in the Universe. Anything alive.

Us humans, we’re good at finding patterns and grouping things. We form tribes. But ultimately, we’re all made of the same stuff. Star stuff.

I feel grateful for being alive today. And lucky I get to do what I do.

Technology can improve people’s lives, but it can also make them worse. Even when our intentions are good.

So I think we all have a responsibility to constantly improve ourselves, achieve mastery, and make this planet a better place for future life.

I buy a lot of books and never read them. Remember Sapiens? Yep. Anyway, here are some books I did read and they are awesome.
