Self-taught engineer: building, analyzing, and breaking systems.
Luis Rosario
About
I'm a self-taught engineer based in Fort Worth, Texas, currently interning at the Child Poverty Action Lab. I started coding young and never really stopped.
It started with simple applications. Then I started using code to analyze things in my own life, and the projects grew from there. I competed in TSA events through my school and a software engineering competition, and each round was a little more ambitious than the last. Eventually I landed on cybersecurity, and it stuck.
Security is the part I actually love. There's a real satisfaction in finding a vulnerability and exploiting it, and a bigger one in knowing that if I find it first, I can help fix it before someone who wants to cause harm gets there. That's also where I learned something about myself: I'm mission-oriented. I want the work to matter to real people, not just function.
Right now I'm going deep into red teaming and reverse engineering, learning how systems break so I can help make them harder to break. From here the plan is to earn my OSCP, then OSED, and eventually the OSEE. I intend to see all of them through.
Outside of work, I'm usually listening to music or playing too much CS2. I'm always happy to connect or collaborate, so say hi on GitHub or LinkedIn.
