Is this my portfolio? Partially, but not as you would conceptualise a portfolio.
Here I want to show only one thing: there are multiple way to solve a problem, but shortly put to solve a problem you must… solve it!
Got a problem (say - explaining assembly without tonnes of LLDB dumps)? Write something that can help you and whoever reads you to simplify their situation. Wanna do binary analysis? Well, write a tool that does it. Wanna learn about Load Commands? Well, then write about them!
If you need me, here I am. I don’t say “I know security” - I say “This is a tool to improve security in a given context”. Which is more than the large majority of IT Sec consultants do (yes, I also betrayed the guild of IT Sec Consultants).
