PORTFOLIO // INFRASTRUCTURE

Infrastructure &
Network Administration

I build and run reliable infrastructure — servers, networking, and the automation that keeps them healthy. Selected builds below.

Selected Builds

Self-hosted // production
MESH // PRIVATE

Private Mesh Networking

Designed and operate a Tailscale-first network architecture. All internal services are reachable only over the private mesh; anything public is an explicit, reviewed exception.

HARDENED // KEY-ONLY

Hardened Remote Access

Migrated SSH to key-only authentication as an unprivileged user, tunneled over the private mesh. Routing verified end to end across multiple machines.

WATCH // ALWAYS ON

Container Monitoring & Alerting

Real-time container health monitoring with alerts on CPU/memory thresholds, OOM kills, and unexpected exits, delivered straight to Discord.

AUTOMATE // EVENT-DRIVEN

Workflow Automation

Self-hosted n8n automation platform wired into internal REST APIs for scheduled jobs and event-driven workflows.

LEAST PRIVILEGE // BY DEFAULT

Rootless Containers

Container workloads run as an unprivileged user with a rootless daemon, shrinking the attack surface of the whole stack.

SINGLE PANE // LIVE

Infrastructure Dashboard

Web-based operations dashboard: live container status, host resource stats, and alerting in one place.

PATCH // ON SCHEDULE

Update Management

Automated container image update checks with scheduled maintenance windows, so patching is routine instead of a fire drill.

Static Site Deployment

Public website migrated to Cloudflare Pages with repeatable, one-command deploys.
