I'm a software developer from Brazil with practical experience in backend engineering, software architecture, and web systems. My focus is on building systems with well-founded architectural decisions, clear domain modeling, and long-term maintainability.

Professional Experience: Currently working as a Full Stack Developer at SIFAT, contributing to the evolution and optimization of Waybe ERP, an enterprise solution for restaurants, retail stores, and gas stations. I work with React on the frontend and Java Spring Boot on the backend, expanding my knowledge across different technology stacks while maintaining a strong focus on architectural principles.

Technical Interests:

• Backend development with Node.js, NestJS and Java Spring Boot
• Layered architectures and separation of concerns
• Explicit domain modeling and business rule enforcement
• Data integrity and relational databases as a source of truth
• Architectural decisions and their long-term impact

I keep both early and recent projects public to demonstrate my technical evolution: from full-stack fundamentals to more architecture-focused systems.
