Mobile architectureComponent governanceAccessible design

I currently work as a Software Architect at XP's Design System (SOMA), contributing to the architectural foundation that underpins mobile engineering.

My work involves structuring how components are born, evolve, and are eventually deprecated, ensuring every technical decision remains clear and sustainable over time. I define standards and formalize directions so the platform grows consistently.

I also build automations that reinforce quality without constraining engineering, and I actively contribute to Flutter component evolution. In parallel, I support squads in the consistent adoption of the Design System, connecting guidelines to day-to-day practice.

Among the initiatives I have led, I highlight the governance model for deprecated components and the consolidation of accessibility as a structural pillar of the system. My focus is to ensure the platform continues evolving with technical responsibility and a long-term vision.
