Experience

Homelab

https://github.com/rizebi/randomScriptsAndProjects
My homelab consists of an Unraid-based server and several Raspberry Pis used for learning, testing, and self-hosting services. It serves as a centralized NAS and a platform for experimenting with infrastructure, networking, automation, monitoring, and security concepts. The environment includes Tailscale, Cloudflare Zero Trust, Prometheus/Grafana, Plex, PhotoPrism, and Syncthing, alongside custom solutions such as Borg-based off-site backups, web scrapers, and a Telegram-powered personal assistant. The setup allows me to continuously explore new technologies and validate architectures before applying them in production environments.
