Let's Code: Programming STATEMENT

Becoming a programmer is deeply connected with the years-long study of cybersecurity, penetration testing, digital forensics, and information security.

It forces me to draw from all disciplines I have learned. It is my test of perseverance, creativity, and knowledge that appeared to be also, rather unexpectedly, the catalyst in my decision to study programming.
