Hello There, I'm JaxT

About me

I'm the kind of person who needs to understand how things work — not just in technology, but in everything. That curiosity is what got me into cybersecurity in the first place, and it's what keeps me going deeper.

I'm an Artificial Intelligence and Machine Learning student at UFPB (Federal University of Paraiba) in Brazil. I spend most of my free time playing CTFs, breaking things apart to see what's inside, and writing about what I find along the way.

What I do

I work as a security consultant focused on offensive security. My work covers penetration testing across multiple domains:

• Web Applications — from classic injection flaws to complex business logic vulnerabilities
• Mobile Applications — Android and iOS security assessments
• Infrastructure — internal networks, Active Directory environments, and cloud configurations
• Application Security — source code review and secure architecture consulting

CTFs and Research

CTFs are where I sharpen the blade. I compete regularly on Hack The Box (Seasons), and I use these challenges to stay current on real-world attack techniques and to push my skills into unfamiliar territory.

This blog is where I document what I learn — writeups, cheatsheets, and the occasional deep dive into something that caught my attention.
