About Me

With over 4 years of experience in cybersecurity, I've dedicated my career to making the internet a safer place. My journey started with a curiosity about how systems work and evolved into a passion for breaking them ethically, of course.

I specialize in discovering critical vulnerabilities in web applications, mobile apps, and network infrastructure. My approach combines technical expertise with creative problem-solving to identify security gaps that others might miss.
