01.About me — Senior Angular Developer

I’m a Senior Angular/TypeScript engineer with 9+ years building enterprise-grade web applications. I’ve worked on pilot operations platforms at United Airlines, financial tools at JPMorgan, and CRM systems at WeightWatchers — always focused on authentication architecture (OAuth/OIDC), UI performance at scale, and shared component libraries that serve multi-team platforms.

I accelerate delivery through AI-augmented development (Claude Code, Cursor, Copilot) while maintaining the architectural judgment AI tools can’t replace. My thesis project integrated LLM APIs into an educational platform with controlled prompts and A/B feature gating.

Currently based in São Paulo, Brazil. Trilingual: Spanish (native), English (advanced), Portuguese (professional).
