I am a Systems Analysis and Development student in Brazil, focused on back-end services, full-stack applications, and software that supports real business workflows.
My recent work covers API design, relational data modeling, authentication and authorization, transactional business rules, automated testing, and Windows-friendly developer tooling. I care about clear documentation and about stating what a project has actually validated.

I am completing a degree in Systems Analysis and Development and deepening my understanding of software architecture, data structures, databases, operating systems, networks, and software engineering practices. I use portfolio projects to turn those subjects into working systems that can be reviewed and tested.
The best way to reach me about software roles or collaboration is through LinkedIn.
