Welcome! 👋

😎 Who I am

Highly motivated and obsessively focused, I guess, is the best way to describe me. I commit myself entirely to every single project I work on because, for me, software development is more than just my job; it is also my hobby and my passion. My main fields of interest are networking, web3 technologies, and cybersecurity.

I’ve been programming since I was 15, and from that point onward, I knew that technology was my vocation. Nowadays, I have the pleasure and opportunity of obtaining a Computer and Telematics Engineering bachelors at the University of Aveiro, which has broadened my view of this field and has been an amazing learning journey. Currently, I attend the Master's in Cybersecurity course at the same university.

Professionally I started as an Undergraduate Student Researcher at Instituto de Telecomunicações's center at Aveiro in the field of microcontroller network communication for the FireTech project, which aims to develop a system of wildfire detection and population warning via existing fiber optics network and local radio station broadcast, respectively. I've since advanced into a Graduate Research Scholarship focusing on the DevSecOps of a Software Defined Network controller for large-scale deployment in quantum-safe environments.

In my spare time, I tend to spend it developing my ideas (of which I seem never to get enough) for innovative systems and applications. I'm also a volunteer firefighter and as such I tend to draw inspiration from my personal experiences in the field of rescue and crisis response for the development of tools that can aid me and others like me to get the job done well!
