darccau is an application security engineer.

I find vulnerabilities for a living and build tools to stop them from happening again. I maintain and develop custom security automation that integrates into CI/CD workflows, helping teams secure code before it ships.

Beyond corporate security, I'm active in OWASP Natal and SunSec, organizing events, researching vulnerabilities, and helping grow Brazil's security talent.

I also write about security, tooling, and communities on my blog.

Whether you're breaking things, building security tools, or organizing communities, I'm here for those conversations.
