Linux + networking heavy: DNS/WHOIS, SSL/TLS, mail deliverability (SPF, DKIM, DMARC), Docker, Kubernetes (K3s), Nginx, Bash, Git.

Kubernetes, K3s, Longhorn, GitOps, observability Prometheus, Grafana.

A set of web based sysadmin utilities (NetworkWhois) and a K3s lab (Longhorn, backups, upgrades) to document practical production patterns.

Collabs on DevOps tooling, self hosted infrastructure, Kubernetes ops, email deliverability, DNS debugging, and Next.js utilities. Happy to review configs, troubleshoot weird issues, or swap ideas.
