Automate. Scale. Secure.

Linux.
Sysadmin.

About

The person behind the uptime.

It started the way it usually does — one server nobody else could keep alive. For over 15 years since, keeping Linux servers, cloud platforms, and hosting environments running for startups, agencies, and developers around the world is simply what I do.

I work solo on purpose — it keeps communication direct and the work accountable. When you hire me, you get the person who actually does the work, not a ticket in someone else's queue.

Currently available for new server, cloud & DevOps work.

Services

What I specialise in.

Three areas where I spend most of my time — and where I can help you most.

  1. Linux Server Administration

    Setup, tuning, and long-term management of Linux servers — including web servers, mail servers, DNS, VPN, control panels like cPanel and Plesk, and everything in between.

  2. Cloud & DevOps

    Cloud infrastructure on AWS, GCP, Azure, and DigitalOcean — combined with CI/CD pipelines, Terraform, Ansible, and Docker to keep deployments fast and repeatable.

  3. Security & Reliability

    Firewall setup, server hardening, SSL/TLS, monitoring, and backup strategies — so your infrastructure stays secure and your uptime stays high.

Process

How I work with you.

Simple, direct process — no hand-holding required on your end.

  1. Understand Your Setup

    I start by reviewing what you have — servers, cloud accounts, codebase, or hosting environment — and identify the fastest path to your goal.

  2. Build & Automate

    I set up, configure, and automate everything — from server provisioning and CI/CD pipelines to monitoring and backups. Built to last, not just to work once.

  3. Hand Over & Support

    You get clean documentation, hardened systems, and ongoing support whenever you need it. I stay available — not just for the job, but for what comes after.

Clients
