## About

```text
At Basis Tecnologia da Informação, I led architecture and engineering for the Federal Comptroller General’s high-traffic Brazilian Transparency Portal. I modernized microservices and core API endpoints to Java 21 and Spring Boot 3.x, and established TDD and unit testing for public auditing endpoints.

At Finaya Tech, I engineered banking and fintech solutions for PIX instant payments and automated customer account onboarding. I designed communication flows across distributed services and modernized legacy microservices with Java 17, Spring Boot 3.x, and MongoDB.

At FCamara Consulting & Training, I led an engineering squad delivering resilient microservices for a multinational pharmaceutical leader. I also helped automate cloud deployments with AWS, Kubernetes, and Argo CD, and implemented observability with DataDog.

Across roles at Thoughtworks, dti digital, Liferay, Pitang, CESAR (Innovation Center), Accenture, Cast Group, and Ivia, I worked on distributed systems, architecture, and backend development. At Thoughtworks, I optimized backend bottlenecks, reducing latency by 20% across core microservices.
