I am a Backend Developer specializing in building scalable APIs and clean architectures. My focus is on software robustness by implementing Hexagonal Architecture, DDD principles, and advanced design patterns.
I master the Spring Boot ecosystem (both MVC and Reactive WebFlux), SQL/NoSQL database management, and I ensure code quality through TDD and Testcontainers. I aim to bring technical expertise and architectural rigor to agile development teams.
