> Meanwhile, my cofounder is rewriting code we spent millions of salary on in the past by himself in a few weeks.
This is one of those statements that would horrify any halfway competent engineer. A cowboy coder going in, seeing a bunch of code and going 'I should rewrite this' is one of the biggest liabilities to any stable system.
Every professional SWE is going to stare off into the middle distance, as they flashback to some PM or VP deciding to show everyone they still got it.
The "how hard could it be" fallacy claims another!
I assume this is because they're already insanely profitable after hitting PMF and are now trying to bring down infra costs?
Right? RIGHT?!
