About

The person behind the uptime.

It started the way it usually does — one server nobody else could keep alive. Since then, 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.

How I work with you.

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

  • 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.

  • 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.

  • 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.

What I specialise in.

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

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.

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.

Security & Reliability.

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