Systems & Infrastructure Engineer

Hello, I'm Sabrina

I build

I build and monitor reliable infrastructure — from cloud deployments on AWS to full monitoring stacks with Nagios, Prometheus, and Grafana. I turn complex systems into elegant, observable solutions.

Passionate about systems that just work.

I'm a systems and infrastructure professional with a passion for building robust, observable, and secure environments. My expertise spans cloud infrastructure, monitoring, and automation.

From setting up Nagios on Ubuntu to securing servers with SSL certificates and configuring reverse proxies — I love the challenge of making complex systems reliable and transparent.

When I'm not configuring servers, I'm exploring new tools and technologies to level up my infrastructure game.
