I am an engineer who develops himself in language-independent concepts related to software, does research in the field of Cyber Security, is interested in Malwares, and basically self-learns and applies all of it.

My principle, “To learn to defend, you need to know how to attack”, today I am conducting research on current cyber threats. On the other hand, I am working on system languages. Because I know that low-level languages such as Assembly and C are the basis of all information systems. After all, we work with 1s and 0s
