What I'm looking for

I’m looking for a Full Stack role where I can own end-to-end features, build secure and high-performance systems, and collaborate with product and engineering teams. I want challenging, mission-critical work with real-world impact and strong engineering practices.

I’m a Full Stack Developer who thrives in fintech, health-tech, and banking environments—where compliance, security, and reliability aren’t optional. I’ve contributed to mission-critical systems in Brazil’s public banking sector while building internal web platforms under strict standards.

Across my roles, I’ve owned features end-to-end: integrating REST APIs to legacy constraints, developing backend services in Java and C#/.NET, and delivering polished frontends. I also built and scaled a multi-tenant SaaS platform for occupational health management, including an analytics dashboard with role-based access control and data privacy compliance.

I bring a strong engineering backbone—automation with JUnit/Mockito and Selenium, CI/CD with Jenkins, and event-driven design using Apache Kafka and Apache Camel. I’m also research-minded, having built data pipelines with Python (Pandas, PyTorch) and worked on transformer/NLP approaches for pattern recognition and relational database schema understanding.
