What I'm looking for

I seek roles focused on mobile and blockchain security where I can apply reverse-engineering and auditing skills, contribute to detection strategies, and grow in Web3 security within a collaborative, research-driven team.

I am a security engineer with 3+ years of reverse engineering experience and a strong focus on Android and Windows reversing, penetration testing, and vulnerability analysis.

I have hands-on expertise in malware analysis, detection strategy development, and exploitation trend research, and I maintain a strong CTF background with proven reversing and patching skills.

Recently I have concentrated on blockchain smart contract security and auditing, actively learning Solidity, DeFi protocols, and common vulnerability patterns while practicing classic Solidity vulnerabilities through Ethernaut challenges.

I am proficient in Python and a wide range of reverse-engineering and security tools (Frida, IDA Pro, Ghidra, JEB, Apktool, Unidbg, Unicorn, Angr, Z3) and have applied these skills at Meituan to improve device risk detection and mobile security defenses.
