+
+## Summary
+
+SRE managing a 7-node distributed fleet with 256 systemd services, 52 automated tasks, and self-healing autonomy. Maintains 48+ production domains, 99 Cloudflare deployments, and a daily KPI system tracking 60+ reliability metrics across 9 data sources.
+

+
+## Experience
+
+### BlackRoad OS | Founder & SRE Lead | 2024–Present
+
+**Reliability & Uptime**
+- Operate 5 Raspberry Pi edge nodes + 2 cloud VMs with WireGuard mesh connectivity
+- Implement self-healing cron automation: heartbeat every 1 minute, heal cycle every 5 minutes
+- Monitor and resolve 12 failed systemd units across fleet with automated restart policies
+- Manage 48 Nginx reverse proxy sites routing traffic to backend services
+
+**Incident Response**
+- Identified and resolved thermal throttling (73.8°C → 57.9°C) caused by runaway Ollama loops
+- Fixed undervoltage issues across Pi fleet via config.txt tuning (+95mV recovery)
+- Discovered and removed obfuscated cron dropper (security incident on Cecilia)
+- Resolved swap exhaustion (100% on Cecilia) by identifying memory-hungry services
+- Migrated leaked credentials from plaintext crontabs to secured env files (chmod 600)
+
+**Monitoring & Observability**
+- Built 9-collector KPI system: GitHub, Gitea, fleet, services, autonomy, LOC, local, Cloudflare, deep GitHub
+- Track 60+ metrics daily: commits, fleet health, temperatures, swap, processes, connections
+- Distributed tracing database with nanosecond-precision spans
+- Per-node SSH health probes with Python-based remote execution
+- Power monitoring deployed to all nodes (cron every 5 minutes, persistent logs)
+
+**Infrastructure Management**
+- 14 Docker containers via Docker Swarm with leader election
+- 11 PostgreSQL databases with automated backup
+- 9 Tailscale mesh peers for secure cross-network access
+- 4 Cloudflare tunnels routing 48+ domains to fleet services
+
+**Capacity Planning**
+- Fleet: 20 GB RAM, 707 GB storage, 52 TOPS AI compute
+- Identified and disabled 16 skeleton microservices freeing 800 MB RAM
+- Cleaned 19 GB of stale GitHub Actions runner directories
+- Power optimization: conservative CPU governors, WiFi power management, GPU memory reduction
