Security Posture

Security is practice, not a badge. Here's what I actively maintain.

  • ✓Caught and documented a DPRK-linked supply chain attack targeting developers via LinkedIn.
  • ✓All repos: branch protection, required PR reviews, and secret scanning enabled.
  • ✓Self-hosted infra: Gitea + Orca — zero third-party supply chain exposure.
  • ✓OpenTelemetry tracing on all production services via SigNoz.
