Hi, I'm Gael Rubio 👋

Systems Engineering Student | Firmware | Linux Infrastructure | Cybersecurity

👨‍💻 About Me

I enjoy learning through fully hands-on projects: from setting up and administering Debian-based Linux servers in headless environments, configuring local networks, and developing automation scripts, to working with firmware and embedded systems.

I dedicate part of my time to developing tools for microcontroller-based devices, especially projects involving automation and the implementation of lab environments with Linux servers.

If a project connects the physical world with code, “me lo echo”. 💻🔧
