About Christophe

I primarily work on the Debian layer of servers with the construction of the SYSMASTER stack (Puppet system administration, with an optional Webmin/Virtualmin integration).

Perhaps you have aDjango**, **WordPress**, or **Dolibarrapplication, but no one to truly take care of it, due to lack of time or advanced expertise. Or worse, someone is taking care of it, but you don't really know what's running or how.

To ensure service control, I work with **Puppet**. Not just for show, but because it's the only serious way to maintain server control over time. Every configuration is written, readable, and belongs to you. If I disappear tomorrow, you can continue without me.

Would you be able to rebuild your server from scratch? Do you truly understand what's running on it right now?

No juniors to supervise, no agency hiding what they do. You don't have to explain the basics or monitor every intervention.I take charge, you move on.

I handle thecomplete system administrationof yourDebianservers: verified backups, security, updates, incidents. Autonomously, without you having to follow up.

And if the problem comes from your Django application rather than the server, I can intervene directly as support.No need for a third-party provider.

I work exclusively under **GNU/Linux**, with fully encrypted storage. Your data does not transit through a system that is inherently vulnerable.

Good luck and see you soon. Christophe.

Experience

  • Récupération d'une partie XFS corrompue d'un serveur CRITIQUE
    SysAdmin
    April 2026 - April 2026
    Things don't always run as expected.

    The server (which includes a Domino Docker instance) was backed up, but one fine morning, after a brutal host server shutdown, the VM got stuck during boot.

    My client contacted me urgently, a bit panicked.

    The XFS repair command didn't work, but with the help of Claude (who, for once, wasn't hallucinating), I checked the manual before running the command (always verify what Claude says) and finally, a magical option allowed me to repair the system and restart the server.

    And then everything ended well.

    Keep your mind at ease by entrusting your servers to a reliable provider, and stay focused on your core business.

    I manage the entire system layer that hosts your Prestashop, WordPress, or other PHP software websites.

    The focus is on system backup and security.
    Each WordPress site can be optimized for speed.

    Double bunker backup is available as an option in addition to incremental backup.

    Websites are isolated from each other for greater security.
    System updates are performed to prevent any intrusion.

    We only access the ROOT account from an ultra-secure and fully encrypted workstation (no Windows, no macOS).

    You no longer need to worry about your servers.

  • Infogérance serveur WordPress/WooCommerce avec maintenance
    Sysadmin, Expert Puppet, WordPress Maintenance
    January 2025 - Today (1 year and 5 months)
    Your WordPress is a business asset, not just a storefront.

    For a WooCommerce store or a members area, technical approximations come at the cost of lost revenue. If you manage your server alone or "babysit" a junior provider, you carry a mental load that isn't yours.

    My goal: to stop your infrastructure from consuming your brainpower.

    Zero black box: Your configuration is entirely coded and versioned. This ends the dependency on human memory and guarantees a transferable asset.

    Active vigilance: An automated system continuously checks your server's status to detect and correct any drift.

    Senior autonomy: I act as an expert partner. You don't need to supervise me; I take responsibility for stability.

    Don't let a critical WordPress become your breaking point.
