Portfolio

Scaling mobile design at Magalu via a design system

Native mobile system for iOS and Android: foundations, components, and governance without halting product delivery.

Unifying the SaaS experience at Magalu

Experience direction, tokens, and a contribution model to accelerate delivery across multiple verticals, with shared standards and platform scale.

How we built a multi-platform product page that lifted conversion

We turned a duplicated (and inconsistent) PDP into a reusable web-based page, standardized by the design system, and improved the experience based on research.
