Who I am

I'm a Brazilian Senior Full-Stack Engineer with over 9 years of experience shipping production-grade applications across healthtech, e-commerce, and distributed systems.

I'm fluent across the whole stack, from React component architecture to NestJS microservices, serverless Lambda pipelines, and cloud infrastructure on AWS and GCP.

What sets me apart isn't just technical breadth but an ownership mindset. I think in systems, ship with confidence, and care deeply about the business impact behind every line of code.

Engineering principles

The beliefs that shape how I write, ship, and think about software.

01

Clean, maintainable code

SOLID principles, DRY patterns, and readability that future teammates will thank you for. Code that survives beyond the sprint.

02

Strong testing culture

From unit to E2E, confidence through coverage, not prayers. I scaled E2E coverage from 30% to 80% in production.
