My best work starts with something tangled that needs to feel obvious.

Designing behavioral systems that decide whether people stay.

Pieces where the interface
has consequences.

Mjolnir

A streaming platform inherits the habits of the apps its users already live in. The work was choosing where to keep those conventions and where to break them.

About

I care about
what cannot be seen.

The moment a habit forms.
The reason someone returns
long after curiosity fades.

The place where intention
quietly becomes behavior.

I don't design screens.

I design systems that people carry
long after they close the app.
