I am a software engineer and cybersecurity professional with nearly five years of experience building and maintaining healthcare systems using Java, Kotlin, TypeScript, Spring Boot, GraphQL, React, PostgreSQL, and Oracle.
I have hands-on cybersecurity experience from an RNP residency, where I performed adversary emulation, penetration testing, vulnerability assessments, attack-surface analysis, and Linux hardening in corporate environments.
I have a strong background in secure software development and source-code review. I authored 179 pull requests and reviewed 452 pull requests, assessing regressions, performance, versioning, and security in a SonarQube-gated CI/CD workflow.
I work comfortably with Linux, Kali Linux, Docker, GitHub Actions, Git, GitHub, and AI-assisted development tools such as Claude Code. I also build public security and developer-tooling projects, including inviscan and MobileFuzzingPOC.
I am a native Portuguese speaker with native/bilingual English proficiency and experience collaborating remotely with international teams. I am available now and interested in remote cybersecurity, security engineering, and secure software development opportunities.
