Claro S/A

  • ▹Develop and modernize scalable enterprise systems using Java (Spring Boot) and Angular (TypeScript)
  • ▹Apply software architecture best practices, SOLID principles, and design patterns to ensure maintainable codebases
  • ▹Implement messaging and caching solutions with RabbitMQ and Redis for high-performance distributed systems
  • ▹Optimize backend performance and database queries across SQL/NoSQL environments, achieving over 40% performance improvement in a multicloud billing project (AWS, Azure, Huawei, Oracle)
  • ▹Collaborate closely with multidisciplinary teams to enhance software reliability, scalability, and innovation

About Me

Fullstack developer focused on building and modernizing robust, scalable systems—combining Java (Spring Boot) on the backend with Angular (TypeScript) on the frontend to deliver reliable, business‑critical software.

Hands‑on experience with messaging (RabbitMQ), caching (Redis), and SQL/NoSQL databases, applying SOLID and design patterns like Command and Factory to achieve low coupling, high cohesion, and maintainable codebases.

Recently contributed to a multi‑cloud billing platform (AWS, Azure, Huawei, Oracle), migrating the frontend to Angular 18/TypeScript and optimizing legacy Spring Boot services—resulting in a 42.3% improvement in processing throughput and a more sustainable codebase.
