The lab

Systems I build after hours.

A self-hosted home lab for orchestration, storage, ML-powered media and agentic automation, on real hardware. It’s where I test ideas before I bet a team on them.

Kubernetes on Raspberry Pi

A bare-metal cluster with control-plane and worker nodes for experimenting with orchestration and deployment strategies.
