Hello, my name is

Jimin Kim.

I dive deep into systems.

Software Engineer & Researcher based in South Korea.
SW Maestro 15th (Youngest) | BoB 14th Vulnerability Analysis (Completed)

My interests lie in FFI, GC, and Compilers. I actively contribute to open source and study to ensure I remain irreplaceable by AI. I strive to be an engineer who is not bound by specific technologies but adapts to solve complex problems.
