Design Systems & Engineering, Behavioral Design | Turning ambiguity into systems that compound · Remote, LATAM

Brazil
Message

I take on problems that don't have a clear shape yet, and restructure them until solutions start feeling inevitable. I think in systems, end-to-end — discovery through delivery, design through the code that ships it. I specialize in 0 to 1 product design, design systems, and behavioral design that shapes how people engage, activate, and return.

► Co-designed MySecurity, a B2B2C consumer security mobile app for Segware — designing and coding the white-label token architecture behind 100+ branded apps — Segware's most profitable product and a competitive moat across Latin America for 10+ consecutive years.

► Redesigned Couchsurfing's engagement model (14M+ users) around Hook Model triggers — Instagram Stories-like posts and a people-places-interests feed triad, partially echoed in Couchsurfing's 2026 rebuild — and designed and coded its Design System, including the first React and Storybook implementation.

► Solo-led the UX for WEG's global electric-motor quotation platform, one of the world's largest electric-motor manufacturers (135+ countries) — unifying three competing tools while reconciling sales' need for speed and engineering's need for precision.

Product trio fluent:
PM and engineering fluency, not just design — a strong collaborator on a full team, self-sufficient on a small one.

A modular systems thinker:
I built fully tokenized design systems years before Figma introduced native variables.

Commercial instinct:
I've led marketing teams, reshaped brand strategy, and sold my own product designs directly to customers.

A "block-shaped generalist" (Jenny Wen):
Design, strategy, marketing, code — deep enough in each to move between them without a handoff.

Business, discovery & behavioral fluency:
Users at the center — habit formation, activation, and retention, all shaped around what people actually want.

The right thing, built right:
Craft and direction, always together — grounded in how people experience a product, not just how it functions.

Game thinking (not gamification):
I don't optimize screens. I optimize the loop.

As AI takes on more delivery, what stays scarce is judgment — the questions worth asking, the behavior worth shaping, the mental models people already carry. I use AI to sharpen that judgment, not to replace it. I join teams as a partner — their product's outcome becomes mine too.
