People don't read interfaces. They feel them.
The detail is the product: 200 ms, a 6 px blur, a button that shrinks when you tap it.
Motion explains where things come from and where they go.

I'm Agustín. I build products end to end.
I'm a full-stack engineer in Buenos Aires, today a senior React Native engineer at SQUIRE. Since 2020 I've built web apps, mobile apps, APIs and the infra under them, for companies like Galeno and Givers and clients in the US and Argentina.
On the side, I make my own apps from the idea to the store: the design, the app, the backend and the launch. More than 15,000 people have downloaded them.
I care about the small stuff. That's where a product starts to feel right.
