Business Analyst · Requirements Engineering

I turn complex needs into clear, testable, auditable requirements.

9+ years at the intersection of business and technology, mostly in regulated, high-criticality environments: health, energy and tax (ANVISA, Petrobras, SEFAZ-PB).

About

Who I am

Systems Analyst focused on Requirements Engineering. I work end to end in software delivery: I understand the business problem, model processes, write the requirements and follow through to validation.

I move naturally across the roles of business, requirements, process and systems analyst and Product Owner, because they share one foundation: removing ambiguity and creating value. MSc student in Computer Science (UFPB), researching LLMs applied to Requirements Engineering.
