About Me

Hi, I’m Nithin Kumar - A Penetration Tester / Cybersecurity Analyst.

I’m curious about how systems work, how attackers break them, and how defenders secure them.

My learning philosophy is simple:

Learn by doing.

That means solving labs, experimenting, breaking things, fixing them, and improving through hands-on practice.
