Hello All 👋

I'm Hamdan Trisnawan, also known as ryosta. A student deeply interested in Networking and Cyber Security. I enjoy analyzing infrastructures, understanding how systems communicate, and exploring security weaknesses to make them stronger and more resilient.

Actively learning about network engineering, system security, penetration testing, and Capture The Flag challenges to sharpen my analytical and defensive mindset. I also explore software development as a complementary skill to support my security journey.
