Personal projects
- A custom homelab dashboard. Everything on one screen, on mobile too. scrypt passwords plus TOTP, CSRF checks, a strict CSP and a least-privilege Proxmox role.
- Hardening with Lynis. The hardening index rose 7 to 11 points on every system, the host from 62 to 72.
- Backups and monitoring. I hear about an outage before I notice it, and every service can be restored from last night’s backup.
- Remote access with a single open port. The router only exposes the VPN port. Internal dashboards are invisible from outside yet use valid HTTPS.
- Self-hosted cloud and media. Files, photos and films at home, no monthly fees, and all of it inside the daily backups.
- This site, secure by design. Pages of a few KB, no cookies or third parties, deployed automatically on every change.
