Frontend software engineer at BTG Pactual building a versioned Server-Driven UI component library and high-volume onboarding grids.

Brazil
Message

At BTG Pactual, I’m working on a multitenant onboarding platform in Angular 20, including a versioned shared library that renders dynamic forms from JSON contracts. I’ve also developed high-volume data grids and contributed to the Colombia onboarding flow, integrating regulatory rules with REST APIs.

At Itaú Unibanco, I built the foreign-currency transfer flow and a shared component library used by more than five squads. I also migrated Angular 15 to 18, improved build and test performance, and cleared the accessibility backlog with WCAG 2.1 guidance adopted by other squads.
