Hi! Welcome to my personal page. I'd like to show my work to people around the world. It's a big oportunity to do a better work too.

I love analysis and security research in everything. Actually, I'd like to find the vulnerabilities in all of applications and protocols, in fact the ways to influence. Feel free to take a look around our site, take a look.

I believe the below sentence :
