Message

At ACS, I test production web and API applications, review code, and threat-model systems with STRIDE. I integrate security scanning into CI/CD and work with engineering teams to remediate vulnerabilities across staging and production.

My vulnerability research uncovered a Critical authenticated RCE in borg-ui and a DNS-rebinding SSRF in pdf-reader-mcp, both credited in published GitHub advisories. I also contributed merged security fixes to NVIDIA garak and MLRun, and built tools for AppSec findings triage and Linux vulnerability assessment.
