Irdi I.

I'm a Linux System Administrator specializing in self-hosted infrastructure, Nextcloud, and open-source technologies. I help businesses, nonprofits, and organizations deploy, migrate, secure, and maintain reliable Linux-based systems. Whether you need a new Nextcloud installation, a complex migration, performance tuning, or ongoing server administration, I deliver solutions that are secure, maintainable, and built for long-term reliability. My expertise includes: • Nextcloud deployment, upgrades, migrations, backup and disaster recovery • Linux server administration (Ubuntu, Debian, Rocky Linux) • Docker and Docker Compose • NGINX, Apache, Caddy, OpenLiteSpeed • PostgreSQL, Mysql, MariaDB, and Redis • Keycloak, OpenID Connect (OIDC), and Single Sign-On (SSO) • Reverse proxies, SSL/TLS, DNS, and networking • System hardening, monitoring, automation, and troubleshooting I've delivered projects involving Nextcloud deployments, Keycloak/OIDC authentication integrations, BigBlueButton infrastructure, cloud migrations, and production Linux environments for organizations of varying sizes. As an active contributor to Free and Open Source Software (FLOSS), I value solutions that are transparent, secure, and sustainable, not vendor lock-in. If you're looking for someone who can solve complex Linux infrastructure and Nextcloud challenges efficiently while communicating clearly throughout the project, let's discuss your project.
