Systems & network administrator — ASIR · finishing a 400h internship (FCT) at Zataca Systems, Elche, Spain.
Based in Torrevieja, Spain — open to relocation.
- ASIR — Administración de Sistemas Informáticos en Red (higher vocational degree in systems & network administration).
- Hands-on with Linux, Docker, Proxmox, networking, security and monitoring.
- I like building small, self-hosted tools that make infrastructure easier to see and operate.
- Open to: sysadmin, DevOps, networking, cloud, infrastructure.
End-to-end deployment of a Wiki.js service on Docker Compose (PostgreSQL + Wiki.js + Nginx) over a hardened Debian VM. Two isolated networks, named volumes, healthchecks, automated backups with retention, monitoring and a tested restore procedure. My ASIR final project — the one that ties everything together.
Stack: Docker Compose · PostgreSQL · Nginx · Debian · Bash · cron
Idempotent Bash script that turns a fresh Debian server into a secure baseline: sudo user + SSH key, key-only SSH (with a lockout guard), UFW, Fail2Ban and automatic security updates. Real --dry-run and per-step flags.
Stack: Bash · Debian · SSH · UFW · Fail2Ban
Visual LAN scanner on top of nmap: point it at a CIDR, see who's there, browse the topology and diff scans over time. Runs in Docker with host networking; multi-arch image on GHCR.
Stack: Node.js · nmap · SQLite · Docker (host net) · GHCR
Visual analyzer for iptables / ip6tables / nftables / ufw rulesets — paste a dump, see the structure. Packet tracing across the full NAT/filter pipeline and a linter for 8 common ruleset smells. 100% client-side.
Stack: JavaScript · client-side · GitHub Pages
Visual analyzer for docker-compose.yml — paste a compose file, see the architecture (services, networks, volumes, ports). Security linter, Dockerfile inspection and multi-file extends/include merging. Client-side, no backend.

Self-hosted monitoring dashboard: add a host by IP/hostname and watch it in real time — ICMP/TCP/SSH with live CPU/RAM/disk metrics, threshold alerts and history charts. Published to Docker Hub.
