I've gone through the same process, not so much that I don't think I would be worth considering, but serious code and documentation examples aren't something I can really give out given that they're proprietary. this last winter I started a whole guest-kernel based syscall intermediation and distribution framework in rust just for the application. with all kinds of design documents. I was about 30% finished by the time I landed a job somewhere else :)
but I still applaud the intent. I self-selected out by giving into scope creep
