Linux sysadmin

    Linux administration for my projects and production websites

    I run and administer the Linux server behind this portfolio, connected project backends and the company websites gravyrochlaser.se and gravyrhandeln.se. The work covers server setup, Nginx, HTTPS, databases, deployments, logs, backups and keeping the services online.

    Company website hosted and administered on Linux

    I run the production environment for the engraving company website on a Linux server. The setup includes Nginx reverse proxying, HTTPS, PHP service management, upload handling, admin access and log-based troubleshooting.

    Production web shop operated on Linux infrastructure

    I administer the server environment behind the web shop, including the Node/Vite application, Stripe-related services, order handling, admin tooling, process restarts and production monitoring.

    What I administer

    The production work behind the websites

    Linux server operation

    I maintain the server environment that runs the portfolio, project backends, databases and company websites.

    Service administration

    Backends and web apps are managed as services with restart behavior, logs and checks so they continue working after server restarts.

    Networking and HTTPS

    Nginx, DNS, HTTPS/TLS and reverse proxy configuration connect the public domains to the correct internal services.

    Databases and storage

    PostgreSQL databases, uploaded files, logs and backups are part of the production setup I operate and troubleshoot.

    Linux production workflow

    From domain to running service

    The public websites are only the visible part. Behind them I manage the Linux host, route traffic through Nginx, run apps and backends as services, connect databases and keep track of logs when something needs to be fixed.

    This includes the portfolio projects, the AI shopping backend, the chatbot/admin API, PostgreSQL-backed services and the production environments for the two engraving business sites.

    Keeping the services usable in production

    Service management

    Applications and backends are run as managed services, with restart behavior and logs that make production issues easier to trace.

    Secure access and HTTPS

    The setup uses HTTPS/TLS, SSH-based administration, reverse proxies and separated internal services exposed through controlled public routes.

    Monitoring and logs

    Server stats, service status, logs and request traces are used to understand load, spot errors and fix problems quickly.

    Databases and backups

    Database-backed apps, uploaded assets and service data are part of the infrastructure I maintain and protect with practical backup routines.
