Public Repository Catalog

A structured index of my public projects, organized by domain, project type, and conservative maturity labels. The catalog excludes private repositories and temporary pull-request forks; the maintained Spanish OWASP WSTG translation is the only fork included.

The catalog is based on repository metadata and documentation and does not claim production readiness, regulatory compliance, or complete security coverage unless a project explicitly documents those facts.

Languages

  • Spanish: Native
  • English: B2 (CEFR)
