About me

More than
a job title

I’m Johanes. I design products, then make sure they survive the trip into code. Most of my work has come through agencies — consumer apps, financial platforms, internal tools, and plenty that never had a public face.

Classic rigour, lean tempo: research, define, prototype, test — none of it skipped, all of it compressed. What I care about most is the moment a design stops being a picture and becomes something a team can build.

When I’m not designing

I think the people worth working with are interesting outside the work too. So: a bow, a pair of running shoes, an oven that sees more action than it should, and a cat with strong opinions.

Cat person

Cat person

Non-negotiable. She supervises most of my work and contributes nothing.

Hiking

Hiking

Long walks uphill with too much in the bag. Best thinking I do all month.

Baking

Baking

Cookies, mostly. The one discipline where following the spec exactly is the whole craft.

The gym

The gym

Progressive overload is iterative design with heavier feedback.

Archery
Repetition until the boring part becomes the good part.
Cooking
Improvised, unlike the baking — this is where I ignore the spec.
Running
Slowly, and with great commitment to finishing.
Reading
Two books at once, usually finishing neither on schedule.
Markets
Stocks, crypto, and whatever web3 is doing this month. Not a side interest I picked up from the work — it's why I went looking for the work.

If you’re after someone who can hold the user’s side of an argument and then go build the thing — say hello.
