✅ Supported Linux Distributions

I work with most major Linux distributions, including but not limited to:

  • Debian family: Debian, Ubuntu (16.04–24.04+), Linux Mint, Pop!_OS
  • RHEL family: CentOS, AlmaLinux, Rocky Linux, RHEL, Oracle Linux
  • Other popular distros: Fedora, openSUSE, Arch Linux, Manjaro
  • Server environments: Headless servers, command line only, container hosts

If you’re not sure which distro to choose, I can recommend the best option for your use case (stability vs. bleeding edge, package ecosystem, support cycle, etc.).

1. Linux Server Installation & Provisioning

Whether it’s a new VPS, bare-metal server, or cloud instance, I can:

  • Install and configure a clean, minimal server tailored to your needs
  • Set up users, groups, SSH keys, sudo, secure remote access
  • Configure firewall (ufw, firewalld, iptables/nftables)
  • Set correct timezones, locales, hostname, DNS
  • Optimize storage: LVM, RAID, separate partitions, tmpfs if needed

Use cases:

  • Web hosting servers
  • Application/API servers
  • Internal tools, intranet, or business apps
  • Game servers or special-purpose services

2. Linux Desktop & Laptop Setup

For everyday Linux users & power users:

  • Install Linux or dual-boot with Windows/macOS
  • Setup drivers for Wi-Fi, Bluetooth, audio, graphics, printers
  • Customize GNOME, KDE, XFCE and other desktops
  • Optimize laptops for battery life & performance
  • Configure essential apps: browsers, office, email, password managers, dev tools

I can also provide 1:1 training on basic and intermediate Linux usage.

3. Security Hardening & Best Practices

Security is not optional on public servers. I can:

  • Harden SSH (keys, disable root login, anti-bruteforce, ports)
  • Configure firewalls and network rules
  • Set up Fail2ban or similar tools for SSH/web login protection
  • Apply and automate security updates
  • Configure sudo policies, audit logging, and lock down unnecessary services
  • Enable full-disk or data-at-rest encryption where appropriate

Optional security reviews and periodic audits are also available.

4. Databases: Installation, Tuning & Backups

I work with popular open-source databases:

  • Relational: MySQL, MariaDB, PostgreSQL
  • NoSQL / Key-Value: MongoDB, Redis

Services include:

  • Fresh installation and secure configuration
  • User/role management and IP access rules
  • Performance tuning (buffers, indexes, connection limits)
  • Designing basic backup & restore strategies
  • Setting up automatic backups (daily/weekly, off-site, encrypted)
  • Migrating databases between servers or providers

5. Web & Application Stack Deployment

I can deploy and configure full application stacks, including:

  • Web servers: Nginx, Apache, Caddy
  • Application runtimes: PHP-FPM, Node.js, Python (Gunicorn/Uvicorn), Go
  • Reverse proxies & load balancers
  • SSL/TLS certificates: Let’s Encrypt, auto-renewals, HTTPS redirects
  • Deploying:
    • Standard websites (WordPress or other PHP apps)
    • APIs and microservices
    • Single-page apps with a backend (Node/Python/PHP/Go)

I can also handle custom app deployment from your GitHub/GitLab repo.

6. DevOps, Automation & CI/CD

To make your infrastructure repeatable and reliable:

  • Write Ansible playbooks to automate server setup
  • Build simple but effective CI/CD pipelines using:
    • GitHub Actions, GitLab CI, or other tools
  • Implement zero-downtime or low-downtime deployments
  • Containerization with Docker / docker-compose / Podman
  • Optional: lightweight Kubernetes (K3s, MicroK8s) for advanced use cases

7. Monitoring, Backups & Ongoing Maintenance

For clients who need long-term stability, I offer:

  • Monitoring setup (from simple tools to Prometheus + Grafana)
  • Disk, CPU, RAM, network, service uptime checks
  • Log rotation, cleanup and retention
  • Automatic system updates and kernel upgrades (with planning)
  • Scheduled health checks and reports

These can be packaged as monthly maintenance plans customized to your needs.

8. Troubleshooting & Emergency Support

If something is broken, I can help diagnose and fix:

  • Server not booting, stuck after updates, GRUB issues
  • High load, slow performance, memory leaks
  • Web apps down, 502/503 errors, SSL issues
  • Database connection problems, slow queries, lockups
  • Network/firewall misconfigurations
  • Broken packages, repository conflicts, dependency hell

Emergency / priority support can be arranged depending on urgency and availability.

9. How the Remote Work Process Works

  1. Initial Contact:
    You describe your problem or project (server specs, provider, goal).

  2. Assessment & Quote:
    I review requirements, ask any essential questions, and provide:

    • Estimated time/complexity
    • Fixed price or hourly rate options
  3. Access & Work Session:

    • Preferred: SSH access with a non-root user (sudo).
    • Alternatively: supervised remote session using TeamViewer/AnyDesk.
    • You can change all passwords after work is complete.
  4. Verification & Handover:
    We test everything together (services running, performance, security basics), and I provide notes or documentation on what was done.
