What I'm looking for

I'm looking to build scalable, accessible web products, particularly in financial platforms, while leading modern front-end architecture and collaborating with cross-functional Agile teams.

I'm a Senior Software Engineer with over 5 years building production-grade web applications for the financial sector, and Angular has been at the core of that journey — from AngularJS days to the latest Angular 18. At Beyond Soluções, I lead development of investment portfolio management applications, working hands-on with Signals and NgRx to keep state management clean and performant. One project I'm particularly proud of was migrating a legacy AngularJS system into a modern micro frontend architecture, which made a real difference in performance and maintainability for the team. Before that, at Act Digital, I built reactive forms-driven onboarding flows that cut processing time in half. I've also helped shape Orquestra, BTG Pactual's Design System, working closely with UI/UX to build a consistent, accessible component library. While Angular is where I go deepest, I've also picked up React and some backend work along the way (Node.js, NestJS, Java/Spring Boot), which helps me think about the bigger picture when building frontend architecture.
