I’m Andy Kannberg — a senior Linux System Administrator and DevOps Engineer with over 20 years of hands-on experience in complex infrastructure environments. From high-availability enterprise setups to lean, efficient VPS deployments for small teams, I’ve seen (and fixed) it all.
What I do:
- Design and deploy secure, scalable Linux-based infrastructures
- Migrate, troubleshoot, and optimize web stacks (Apache, Nginx, PHP-FPM, MySQL, Laravel)
- Harden servers with tools like fail2ban, UFW, SSH config tuning, Lynis
- Automate provisioning and deployment using Ansible, Terraform and cloud-init
- Work with containerization and virtualization (Docker, KVM, Portainer, VMWare)
- Implement CI/CD flows using Git, Jenkins, Forgejo, GitOps best practices
Whether you need to fix a broken deployment, secure your infrastructure, or automate your server setup from scratch, I bring a reliable, pragmatic mindset with an eye for long-term maintainability.
Who I’ve worked with:
- ASML (as DevOps Tech Lead, Connectivity Architect, and Software Engineer)
- Municipalities and enterprise IT departments (UNIX/Solaris/Linux infrastructures)
- Startups and small businesses needing fast, reliable and secure web infrastructure
I'm comfortable taking ownership of a project or integrating into an existing team. I communicate clearly, deliver on time, and always aim to solve root causes — not just patch symptoms.
Typical projects I can help with:
- Fixing broken or misconfigured web servers (500 errors, SSL issues, etc.)
- Migrating legacy systems to modern stacks (mod_php to PHP-FPM, Apache to Nginx, etc.)
- Deploying Laravel or custom PHP apps behind reverse proxies with HTTPS
- Automating VPS provisioning and post-deploy setup
- Cleaning up insecure or bloated cloud setups
Based in Hungary, originally Dutch. Fluent in English, Dutch, and German. I work fully remote and adapt easily to international teams.
Let’s keep your infrastructure clean, secure, and fast — so you can focus on building great products.
Available for short- and long-term freelance contracts.
