Linux Sysadmin & Server Management

Infrastructure
Built Right.
First Time.

From a single Linux server to a full cloud deployment — I handle the setup, automation, and ongoing management so you don't have to.

Why clients keep coming back.

99% job success rate. 100+ completed jobs. Here's what makes the difference.

  • Broad, Hands-On Experience

    From web servers and mail servers to VPNs, DNS, control panels, and cloud platforms — I've managed it all in real production environments, not just in theory.

  • Tailored to Your Stack

    No cookie-cutter setups. Every solution is built around your existing environment, your team's workflow, and your actual requirements.

  • Automation First

    I automate repetitive tasks from day one — deployments, backups, monitoring alerts — so your infrastructure runs itself and your team stays focused.

  • Stays Stable Long-Term

    Systems I build are documented, maintainable, and designed to last. Not quick fixes that create more problems six months later.

What you actually get.

Concrete outcomes — not vague promises.

  • Servers That Stay Up

    Properly configured, monitored, and maintained Linux servers — with alerts, backups, and a clear runbook so nothing catches you off guard.

  • Faster, Safer Deployments

    CI/CD pipelines that automate your builds and deployments — fewer manual steps, fewer human errors, faster time to production.

  • Hardened & Protected Systems

    Firewalls, SSL/TLS, access controls, and patch management applied from the start — not as an afterthought when something breaks.

  • Direct, Fast Communication

    You work with me directly — no account managers, no ticket queues. Quick responses via Upwork or email.

Services I provide

A practical overview of what I work on day to day.

Linux Server Administration

Setup, optimisation, and ongoing management of Linux servers — Ubuntu, Debian, AlmaLinux, and more. Includes web servers (Nginx, Apache), mail servers, FTP, DNS, and VPN.

Web Hosting & Control Panels

cPanel/WHM, Plesk, and CloudLinux management — shared hosting environments, account migrations, and server-level tuning for hosting providers and agencies.

Security & Hardening

Firewall configuration (iptables, CSF), SSL/TLS setup, access control, patch management, and server hardening — applied properly from the start.

Monitoring & Reliability

Server monitoring with Prometheus, Grafana, Nagios, or Icinga — with alerting and clear runbooks so you know when something needs attention.

Database Management

MySQL, PostgreSQL, and MongoDB — installation, tuning, backup strategies, and troubleshooting for databases that need to stay reliable under load.

Cloud Infrastructure

Design and manage cloud environments on AWS, GCP, Azure, DigitalOcean, Linode, and OpenNebula — VMs, networking, storage, and cost optimisation.

CI/CD & Automation

Build deployment pipelines with GitHub Actions, GitLab CI, or Bitbucket. Automate provisioning with Ansible and Terraform for consistent, repeatable infrastructure.

Containers & Orchestration

Docker and Kubernetes for containerised workloads — from a single compose stack to multi-service deployments with proper networking and persistent storage.

Virtualisation & Private Cloud

KVM, OpenVZ, and Proxmox environments — VM provisioning, template management, and private cloud setups for teams that need their own infrastructure.

FAQs

Frequently Asked Questions

Find answers to common questions about my Linux sysadmin, server, hosting, and infrastructure services.

Do you manage cPanel or Plesk servers?

Yes. I have extensive experience with cPanel/WHM, Plesk, and CloudLinux — including setup, migrations, account management, and server-level performance tuning.

Which Linux distributions do you work with?

Primarily Ubuntu, Debian, AlmaLinux, and CentOS — but I also work with FreeBSD, CloudLinux, and other distributions depending on the use case.

Can you help migrate my server or hosting environment?

Yes. I handle server-to-server migrations, cPanel account transfers, database migrations, and cloud provider moves with minimal downtime.

Do you work with cloud platforms?

Yes. I work with AWS, GCP, Azure, DigitalOcean, Linode, and OpenNebula — from simple VM setups to more complex multi-region architectures.

Can you set up CI/CD pipelines for my team?

Absolutely. I build and configure pipelines using GitHub Actions, GitLab CI, or Bitbucket — integrated with your existing workflow and deployment targets.

Do you provide ongoing support after the job is done?

Yes. I offer retainer-based support and am available for follow-up work. Most of my clients come back for additional projects — quick responses via Upwork or email.

Can you help with Proxmox or KVM virtualisation?

Yes. I set up and manage KVM, OpenVZ, and Proxmox environments — including VM templates, networking, storage, and user management.

What is your typical response time?

I aim to respond within a few hours during business hours. The fastest way to reach me is Upwork or email.
