Have you seen this yet? It's a letter from Leonardo da Vinci (yes, that Leonardo da Vinci) to a prospective patron. He lists fully 9 paragraphs of way cool things he can do that are relevant to the warfare of the time (portable bridges, bombing strategies, stone flingers, ways of tunnelling into places and so on) and then mentions:
10. In times of peace I believe I can give perfect satisfaction and to the
equal of any other in architecture and the composition of buildings public and
private; and in guiding water from one place to another.
11. I can carry out sculpture in marble, bronze, or clay, and also I can do
in painting whatever may be done, as well as any other, be he who he may.
Given how well he followed through on those last two (this letter was written before his most famous works) you kind of have to believe all the siege/bombardment stuff too.
The article I've linked to has an image of the actual letter - not in English of course - and some lovely commentary on what makes it a good cover letter. It's not really a resume but it sure is a job-getting device. Apparently the Duke did indeed hire him - as a painter, not a fighter. And if you'd like to see it translated into modern day geekery, I spotted that too.
