Projects

+

Things built, broken, and rebuilt.

+
+ +
+ +
+
+

ridgwaysystems.org

+
+ Go + OpenBSD + self-hosted +
+
+

This site. A single Go binary serving a blog, status page, hire page, and admin panel — no database, no Docker, no external dependencies at runtime. Flat Markdown files on disk, HMAC-signed sessions, chroma syntax highlighting. Deployed on OpenBSD behind relayd. The build log covers the whole thing.

Policy-as-Code Firewall Framework

+
+ pf + IaC + security +
+
+

A policy-as-code system for managing pf firewall rules across multiple OpenBSD hosts. Rules defined in structured configuration, rendered to pf.conf via templating, with automated geo-location blocking and rule validation before deployment. Deployed at Triangle Insurance to manage ~200 rules across three firewall segments.

+

ISP Network Monitoring

+
+ Prometheus + Grafana + Go +
+
+

Custom Prometheus exporter that continuously measures ISP throughput, latency, and packet loss across multiple WAN connections. Exports to Grafana for real-time dashboards and alerting. Replaced manual speed tests that only caught outages after users complained. Cut time-to-detect WAN degradation from hours to minutes.

+
+ +
+
+

Homelab Infrastructure

+
+ OpenBSD + Ansible + Terraform + homelab +
+
+

The homelab: fw01 running OpenBSD with pf and WireGuard, two Dell rack servers, VLAN-segmented network (management, servers, IoT, guest), self-hosted Gitea, Matrix, Jellyfin, Prometheus, and Grafana. Fully documented, IaC'd where possible, and used as a test bed before anything touches production.

Zero-Touch Provisioning System

+
+ PXE + Ansible + automation +
+
+

PXE boot + Ansible-based provisioning pipeline for deploying standardized workstation images across Air Force Training bases. Reduced per-machine setup time by 75% and eliminated configuration drift between deployments. Machines boot, pull config from the server, and are production-ready without a human touching them after the initial PXE boot.

Uses

+

Hardware, software, and tools — homelab and daily driver.

+
+ +
+

Hardware

+ +
+
+ fw01 + Firewall / Router +
+

SuperMicro 1U, Intel E3-1230v2, 16GB ECC RAM. Running OpenBSD. Handles all pf firewall rules, VLANs, WireGuard VPN, unbound DNS, and relayd reverse proxy. The critical piece everything else depends on.

+
+ +
+
+ srv01 + Primary Services +
+

Dell PowerEdge R720, dual Xeon E5-2600, 64GB RAM. Main workload server — runs Prometheus, Grafana, Gitea, OpenSMTPD, Matrix/Conduit. Loud and power-hungry, but handles everything without complaint.

+
+ +
+
+ srv02 + Media / Secondary +
+

Dell PowerEdge R710. Jellyfin media server, game server VMs, secondary storage, authoritative DNS (nsd). The workhorse for anything that doesn't need to be bulletproof.

+
+ +
+
+ ws01 + Workstation +
+

Desktop, AMD Ryzen. Daily driver for development, terminal sessions, and homelab management. Running Fedora Linux.

+
+
+ +
+

Operating Systems

+
    +
  • OpenBSD — fw01, this web server. Chosen for its security defaults, pf, and the fact that it does exactly what it says on the tin.
    • +
  • AlmaLinux / Rocky — srv01, srv02. RHEL-compatible for production workloads where SELinux and systemd are expected.
    • +
  • Fedora — Workstation. Stays close to bleeding-edge tooling without being Arch.
    • +
+
+ +
+

Networking

+
    +
  • pf — OpenBSD packet filter. VLANs, NAT, geo-blocking, antispoof. The whole reason fw01 runs OpenBSD.
    • +
  • WireGuard — VPN for remote access. Simple, fast, auditable.
    • +
  • unbound — Recursive DNS resolver on fw01. Validates DNSSEC, blocks ad/tracking domains.
    • +
  • nsd — Authoritative DNS on srv02 for the ridgwaysystems.org zone.
    • +
  • relayd — OpenBSD reverse proxy in front of this site and internal services.
    • +
+
+ +
+

Infrastructure & Automation

+
    +
  • Terraform — Cloud infrastructure (Azure, AWS). Anything that touches a cloud API gets IaC'd.
    • +
  • Ansible — Configuration management for Linux servers. Idempotent, no agent required.
    • +
  • Gitea — Self-hosted git at git.ridgwaysystems.org. Lightweight, fast, no subscription required.
    • +
  • Prometheus + Grafana — Metrics and dashboards for everything. Custom exporters for pf counters, ISP throughput, and hardware sensors.
    • +
  • Nagios — Service alerting. Opinionated but reliable — been running since before dashboards were cool.
    • +
+
+ +
+

Development

+
    +
  • VS Code — Primary editor. Remote SSH extension makes working directly on servers seamless.
    • +
  • Go — Preferred language for infrastructure tooling and this site. Fast to compile, easy to deploy a single binary.
    • +
  • Python — Scripting, automation, quick data processing.
    • +
  • Bash / ksh — Bash on Linux, ksh on OpenBSD. Shell scripts for anything that doesn't need to outlast the week.
    • +
  • tmux — Terminal multiplexer. Multiple panes across multiple SSH sessions, always.
    • +
+
+ +
+

Self-hosted Services

+
    +
  • OpenSMTPD — Mail server. Handles inbound and outbound for ridgwaysystems.org.
    • +
  • Matrix / Conduit — Self-hosted chat. Federated, encrypted. Currently migrating.
    • +
  • Jellyfin — Media server. No subscription, no phone-home, streams anywhere on the LAN.
