Turning security problems
into verifiable engineering.

A little about me.

I study Information Security at Lanzhou University. My interests sit between offensive security and systems engineering: understanding how attacks work and how programs behave, then turning that understanding into tools and workflows that are reliable, repeatable, and useful over time.

I have spent years working on CTF challenges and practical security exercises, alongside building tools in Go and Python. My work includes reverse engineering, penetration testing, and malware analysis. I care less about following a particular technology trend than about problem boundaries, evidence quality, state ownership, and how a system behaves outside a demo.
