About Me
My name is Mario, and I am a Telecommunications Engineering graduate. I started programming during my university years, and since then, I've been learning and building personal projects in my free time.
Currently, I work at a consulting firm automating QA for Meliá Hotels International's core websites. I have also held roles as a Linux systems administrator at a cybersecurity company and as a software developer.
As an engineer, my goal is to build usable and accessible open-source applications, prioritizing the user experience.
