Hi, I’m Rajae

I'm a Cybersecurity & Backend Engineering student based in Jamaica. I study how systems, networks, and software behave, and I build tools to understand these layers more deeply. I’m currently improving my system-level engineering foundation and contributing to open-source security projects.
