## Summary
|
||
|
||
Needed production infrastructure without a team or budget. Built a self-healing 7-node fleet from Raspberry Pis, automated 52 operational tasks, and deployed 99 cloud services — solo, from scratch.

## Experience
|
||
|
||
### BlackRoad OS | Founder & Senior DevOps Engineer | 2025–Present
|
||
|
||
**The Problem: Zero Infrastructure, Zero Team**
|
||
- No existing infrastructure, no ops team, no vendor contracts — needed production-grade systems running 48+ domains on day one
|
||
- Solved by designing a hybrid fleet: 5 Pi nodes + 2 cloud VMs + Cloudflare edge, all connected via WireGuard mesh VPN — total cost under $700 hardware
|
||
- Result: 256 systemd services running across fleet, 48 Nginx reverse proxy sites, 14 Docker containers — all managed by one person
|
||
|
||
**The Bet: Self-Healing Over Manual Ops**
|
||
- Fleet nodes crash, services fail, temperatures spike — manual monitoring doesn't scale for a solo operator running 256 services
|
||
- Built autonomy scripts: heartbeat every 60 seconds, heal cycle every 5 minutes, automatic service restarts on failure
|
||
- Detected a node cooking at 73.8°C from a runaway Ollama loop — auto-isolated the process, dropped temp to 57.9°C without downtime
|
||
|
||
**The Multiplier: 212 CLI Tools**
|
||
- Every repeated task became a tool. 212 CLI tools (121 MB) in ~/bin — deploy, probe, audit, sync, report
|
||
- GitHub-to-Gitea relay syncs 207 repos every 30 minutes. Daily KPI collection tracks 60+ metrics across 10 data sources
|
||
- 99 Cloudflare Pages, 23 D1 databases, 47 KV namespaces, 11 R2 buckets — all deployed and maintained through CLI automation
