I'm a software developer from Brazil with practical experience in web development and a growing focus on backend engineering, software architecture and domain-driven design concepts..
My professional experience started mainly on the frontend, working with React, Angular and Vue.js in internships and real projects. Over time, I became increasingly interested in understanding how systems are structured behind the scenes — how business rules are modeled, how data integrity is guaranteed and how architectural decisions impact long-term maintainability.
Currently, I’m focusing on:
- backend development with Node.js and TypeScript
- layered architectures and separation of responsibilities
- explicit domain modeling and business rule enforcement
- relational databases as a source of truth
I keep both early and recent projects public to clearly show my technical evolution — from full-stack fundamentals to more architecture-focused systems.
