I poke around, break things, fix them, and occasionally convince a server to behave. Mostly just here to see what happens next.

Build. Break. Rebuild. The ouroboros is a reminder that systems are never finished objects: they loop through failure, repair, and renewal. I learn by running the cycle again, making each version more resilient than the last.

01 / Projects

Homelab Infrastructure // 2.0
  • Building a production-style homelab to practice infrastructure security, automation, and observability at scale.
  • Using Ubuntu Server 24.04 LTS with Ansible for configuration management and Docker Compose as the current container layer, with K3s planned later.
  • Planning a secrets workflow with HashiCorp Vault and SOPS, plus Prometheus/Grafana monitoring and Loki logging.
  • Documenting hardware, build decisions, and architecture choices as the system evolves, with GitHub Actions planned through a self-hosted runner.

07 / Profile

I build things that run quietly in the background. I got into tech because I genuinely enjoy figuring out how things work under the hood, and that is still what drives me. My work sits between infrastructure, automation, and backend systems, with a constant search for the next thing to build or break.
