I design AI products around how people actually behave.

I'm Priscila. For 4+ years I've designed products across the US and Latam, from B2B SaaS to retail. My background in social sciences shapes every screen: less cognitive load, less friction, more trust.

Selected work

Complex B2B flows made simple, and calm consumer apps. Each one starts with how people really use the product.

Designing for 95% vs. 60% confidence

AI models aren't equally sure about everything. Most interfaces pretend they are.

Chat isn't the default interface

Unpopular opinion: a chat box is often a sign the design work hasn't been done yet.

About

A social scientist who ended up designing products. I still start every project by asking why people do what they do.

My bachelor's in social sciences taught me to look at behavior before features. I use it to design experiences that reduce cognitive load, cut friction and earn trust, which is exactly what AI products need.

I work in Figma and with AI-assisted workflows every day, from prototyping with real AI output to building front-ends with Claude and Cursor. It makes iteration fast and handoff simple.

How I work

Start from behavior, not features

What do people actually do today? That answer decides the interface, not the model's capabilities.

Prototype the logic, not just the screens

On Pro Telhanorte, a working pricing engine aligned engineering faster than any mockup.

Design the wrong answers too

Waiting, uncertainty and mistakes are core states in AI products, so they get real design.
