Server hardening, networking, containers, and day-to-day sysadmin work on Linux.

Security & Infrastructure

I treat servers and networks as first-class concerns—not afterthoughts. Hardening Linux hosts, understanding attack surfaces, and keeping services reliable underpin everything I ship.

Linux administration, services, and automation (systemd, SSH, firewalls)
Security-minded development—least privilege, patching, and secure defaults
Ethical hacking & CTF practice to sharpen defensive thinking
