🎓 Computer Science student @ UFPE (Brazil)
🔐 CTF team member at LSEC
💡 Passionate about cybersecurity and problem solving — I thrive on understanding systems deeply, breaking them safely, and building them back stronger.
I'm a computer science student focused on practical security — from offensive techniques learned through CTFs to defensive applications like hardening, monitoring, and secure deployment.
I enjoy exploring how complex systems fail, automating solutions, and continuously improving my technical range.
Outside security, I’m also drawn to competitive programming and low-level tinkering, which feed my curiosity for how things actually work.
Programming: Python, C++, Java, Bash, SQL, JavaScript
Security Tools: Burp Suite, pwntools, Nmap, Ghidra, IDA, Wireshark, Binary Ninja, Kali Linux
