Reconnaissance · Vulnerability Assessment · Exploitation

I'm focused on learning cybersecurity through hands-on practice - from reconnaissance and network enumeration to web application security and Linux privilege escalation. I use labs, CTFs, and personal projects to understand how vulnerabilities are discovered, investigated, and documented.

01 About

what I actually do

I'm an Informatics Engineering student focused on building practical cybersecurity skills through hands-on labs, CTFs, and personal projects.

My current interests include network enumeration, reconnaissance, web application security, Linux privilege escalation, and vulnerability assessment. I document what I learn along the way - including how I investigate vulnerabilities, what went wrong, and what I learned from each challenge.

I'm currently building my foundation toward a career in offensive security while continuing to strengthen my knowledge of networks, Linux, and security concepts.
