About Me

I am Sudarsan Palaniappan, a Multi-Cloud, DevOps, Linux, and SOC engineer focused on building secure infrastructure that is practical to operate. My work combines cloud deployment, server hardening, CI/CD automation, SIEM onboarding, and incident-driven thinking so environments stay both reliable and defensible.

  • Design and maintain AWS and Linux environments with an emphasis on automation, uptime, and clean operational workflows.
  • Translate SOC and security requirements into usable detections, onboarding standards, alert tuning, and response runbooks.
  • Prefer delivery that is measurable: faster deployments, clearer observability, fewer false positives, and better day-2 operations.
