I build backend systems, APIs and developer tools with a focus on architecture, scalability, security and reliability.
Currently studying Computer Science at UFC Quixadá and deepening my expertise in backend engineering, distributed systems and Java/Spring Boot.
- Production-oriented REST APIs
- Authentication & authorization with JWT, OAuth2 and RBAC
- PostgreSQL-backed systems
- Scalable backend architectures
- Clean Architecture & modular design
- Caching, rate limiting and background processing
- Dockerized applications and CI/CD
- Full-stack systems when the product requires it
