Summary
DevOps engineer operating a 7-node distributed infrastructure spanning edge devices and cloud, with 52 automated tasks, 256 managed systemd services, and 99 Cloudflare deployments. Builds self-healing systems with automated monitoring, fleet-wide power optimization, and daily KPI collection across 9 data sources.
Experience
BlackRoad OS | Founder & Infrastructure Lead | 2025–Present
Infrastructure Operations
- Operate 5 Raspberry Pi nodes + 2 DigitalOcean droplets with WireGuard mesh VPN connecting all endpoints
- Manage 256 systemd services and 35 timers across fleet with self-healing autonomy scripts
- Deploy and maintain 14 Docker containers via Docker Swarm orchestration
- Route 48+ custom domains through 4 Cloudflare tunnels to backend services
CI/CD & Automation
- Built 212 CLI tools (121 MB) for infrastructure management and deployment
- Maintain 17 Mac cron jobs + 35 fleet timers for continuous automation
- Operate GitHub Actions CI/CD pipelines and self-hosted Gitea (207 repos)
- Automated GitHub-to-Gitea relay syncing every 30 minutes
Cloud Infrastructure (Cloudflare)
