Hello, I am a penetration testing engineer. This is a brief about me. I have several experiences in many fields and I also worked in the labor market, such as back-end (node ​​​​js) and Forty Gate Security. I created 12 applications such as Uber, and I am the one who tested them and worked on the back-end part for them. I created many e-commerce sites and I am also the one who conducted security tests on them.
