Engineering
with purpose.
I'm a Senior Software Engineer with a deep focus on backend systems, specializing in Java and Spring Boot ecosystems. My journey has taken me from Brazil's largest financial institutions to Portugal's consulting landscape.
At J.P. Morgan, I worked on trading systems integrated with B3, Brazil's stock exchange. At Bradesco, I built APIs handling credit card operations for millions of customers. Now at KPMG, I'm working on global projects after contributing to Santander's OneCare platform.
I believe in writing code that tells a story: clean, maintainable, and built to last. Whether it's a microservice handling thousands of requests per second or a React component with great UX, I bring the same attention to quality.
