Well, just thinking about the meaning of the word "exact" can be literal, the level of frustration suggests the emphasis is the highest, it can make the reader understand the meaning of "exact" is a literal irreducible exact, implying no one other than you have the literal exact same experience.
In the end the author expressed his frustration at the lack of input from security professionals, but the words he used were perhaps a little arrogant:
He said "to routinely make preventable mistakes because people with my exact skillset haven’t yet delivered easy-to-use, hard-to-misuse tooling".
I would suggest rephrasing this as a way to make it clear what skills he is referring to, something like "people who are senior security experts". Otherwise it might sound like he is implying that he is the only one who should audit everything, because who else would have the exact same experience that he has had all his life?
