Giovani Cascaes

@giovanicascaes

Frontend engineer at Avenue Code who designed the foundations of an onboarding and activation navigation system.

At Avenue Code, I designed and implemented the foundations of the screen navigation system for an onboarding and activation flow. I also contributed to maintaining the custom UI library, advocating for better accessibility and developer experience.

I built a network-mocking proof of concept so frontend implementation could continue independently of backend availability. In code reviews, refinement, planning, and development, I identified requirement gaps and opportunities to improve accessibility and user experience.

At SoftExpert, I built a React tree component with custom virtualization to support large hierarchical datasets while maintaining responsiveness and performance.

My work has also included contributing to push notifications in a React Native application at Digital Pages, developing UI and API features for a Java-based education application at SENAI, and delivering features and reports for an Oracle PL/SQL ERP application at Projedata.
