Biography

Biography

I've been interested in security since high school. I mainly studied webhacking and pwnable. So I used to do bugbounties for window applications/embedded devices and won award at few CTF.

I went to college for computer science and worked for two companies while in college. I worked for a year at one company as a pwnable security researcher. And the company I worked for for three years is Theori. I started working with webhacking skills in this company, but the company introduced me to blockchain security. During my three years of work, I participated in several web/app service security audits, and a unique experience was auditing the security of a digital asset exchange. In blockchain security, I have participated in security audits of DeFi, mainnets built on Bridge and geth, and newly built mainnets in C# language.

After that, I worked as a security researcher in the KALOS team of Haechi Labs company. Outside of work, I continue to participate in bug bounties and ctfs.
