Itaú Unibanco was operating with fragmented design systems across its brands and segments: multiple libraries, inconsistent patterns, and duplicated work slowing down product teams. As part of a broader strategy to consolidate services into a unified super app, the bank needed a single, flexible design system that could serve all brands without losing their individual identities.
The IDL became the main infrastructure pillar enabling the bank’s most significant digital transformation. I was responsible for the systems and operations layer: component architecture, Figma library structure, token system design, WCAG accessibility compliance, contribution model design, designer onboarding, tooling governance, and the internal education program (Edux Itaú).
This was a large cross-functional initiative. My scope was the design infrastructure: the foundation that made the system usable, adoptable, and maintainable at scale.
