At ConstruConnect Tecnologia LTDA, I make technical decisions for a B2B SaaS platform used by thousands of clients in civil construction. I lead a team of 3 to 7 developers while staying hands-on with the codebase.

I architected an asynchronous messaging pipeline that processes approximately 100,000 public records per day as an independent containerized service on AWS ECS. I also led the platform's payment gateway migration from Hotmart to Asaas, completing the rollout with zero downtime and no impact on active users.

At ConstruConnect, I designed cloud infrastructure and an observability stack, and developed REST APIs and third-party integrations using DDD, Clean Architecture, and microservices. I work with Java, Spring Boot, PostgreSQL, and Redis across the platform.

Previously, as a Development Analyst at Techno Software LTDA, I contributed to enterprise warehouse and logistics systems using Java and Spring Boot, including REST APIs and Oracle Database integrations. I'm pursuing a postgraduate degree in Software Architecture at FIAP, with hands-on projects in Kubernetes, Flyway, TDD, JUnit, and Mockito.
