01 / About

From code to the infrastructure that runs it.

My profile connects product development and operations. I can work from the interface and the backend all the way to deployment, networking and the automation that make a solution genuinely usable.

  • Development

    I build frontend and backend applications and complete products, from the interface to the database.

  • Systems

    I administer Linux, services, networks, containers and infrastructure.

  • Automation

    I automate deployments, repetitive tasks, services and integrations, AI ones included.

02 / Systems · Python TUI

Linux Backup TUI

Full, incremental and differential backups from the terminal.

A Python evolution of Backup Scripts: a curses interface that detects external drives, creates full, incremental or differential backups with tar and automatically restores the required chain.

  • External drive detection with lsblk (USB, removable drives and mount points under /media or /mnt).
  • Full, incremental and differential backups with tar --listed-incremental and .snar snapshots.
  • Restoration that rebuilds the FULL → DIFF → INC chain up to the chosen backup.
  • Integrity checks, a manifest.json per backup, safe cancellation and system paths blocked as restore targets.
  • Python
  • curses
  • tar
  • lsblk

Backup Scripts

Full and incremental backups on Linux (Bash version, main branch).

Bash tools to automate full and incremental backups with snapshots, a date-based structure and safe cancellation.

  • Full compressed .tar.gz backup with inicial.sh.
  • Incrementals based on .snar metadata, detecting the latest snapshot.
  • Date-organised structure for FULL and INC backups.
  • Safe cleanup when cancelling with Ctrl+C.
