ROMAIN SINCLAIR — LINUX SYSTEMS ADMINISTRATOR

I build the systems everything else runs on.

Marketing analyst turned infrastructure engineer. CCNA, RHCSA and Security+ — earned by building, breaking and documenting everything in my own lab.

THE STORY

I didn't start in tech.

I came up through marketing and business analysis. A few years in, I hit a point where I knew the path I was on wasn't the right one. People in my corner had already made the leap into tech — and pushed me to do the same. So I did.

I got my CCNA, RHCSA and Security+. I built production labs running RHEL, Docker, Nagios, GitLab and Bacula — because that's how I learn: by building.

Now I combine deep infrastructure knowledge with the business and communication skills most engineers never develop — and I bring that combination to environments where both actually matter.

operating system

Every service runs on Red Hat–family Linux. Users and access, systemd services, SELinux, storage — the same fundamentals I manage in production.

THE STACK

Every layer, understood.

Most sysadmins live at one layer. A network engineering foundation means I understand the layer my systems sit on — top to bottom.

THE JOURNEY

A decade of momentum.

2024 — now

Linux Systems Administrator

Everything I've been building toward, put to work. Ticket-driven Linux environment — access and authentication incidents, core network services (DNS, DHCP, SSH, NFS, FTP), Apache hardening, vulnerability assessments with Qualys and Lynis, automation with Bash and cron, containers with Docker and Podman, config management with Ansible and Terraform — all version controlled through Git and GitLab.

2022 — now

UX Product Owner

Owned concurrent digital initiatives end-to-end at one of the country's largest energy companies — web, mobile, customer tools — running full Agile cycles with engineering, UX and business stakeholders. Working inside enterprise infrastructure at that scale made it clear: I wanted to build the systems, not just the products on top of them.

2021 — 2022

Digital Marketing Specialist / Business Analyst

The inflection point. Strong on paper — but it made clear I was ready for a path closer to the infrastructure powering everything I worked around.

2018 — 2021

Digital Marketing Specialist / Business Analyst

Built marketing operations from the ground up — grew a social following 50% to 20K, generated 1K+ leads, scaled a podcast to 600K+ downloads. The analytical mindset transferred directly into infrastructure work.

2016 — 2018

Senior Sales Marketing Rep

$1M+ in monthly sales, 97% satisfaction over 22 months. Learned to perform under pressure and speak confidently to non-technical stakeholders — one of my strongest assets as an engineer.
