What I'm looking for

I'm looking for an opportunity to grow in offensive security through hands-on vulnerability assessment, web and system penetration testing, and practical collaboration with experienced cybersecurity professionals.

I'm building practical offensive security skills through Hack The Box, PicoCTF, and pwn.collage challenges, with a focus on web and binary exploitation.

I've compromised 9+ vulnerable machines, including Windows Active Directory environments, and solved 80+ CTF challenges. I perform reconnaissance, enumeration, vulnerability assessment, web exploitation, and privilege escalation in virtualized targets.

I document findings with CVSS scores, proof-of-concept steps, and remediation recommendations. My mathematics background supports an analytical approach to ethical hacking, network security, and continuous hands-on learning.
