Can you get better tools to catch his mistakes earlier?

This seems the obvious solution, but it might be useful to get a specific example from OP to see whether these typos can be reliably caught be automation, or if human eyes are required.

Updated with an example. We do, in fact, automate stuff and improve our processes, though nothing's ever perfect.

It's the sheer 'randomness' and 'creativity' of the ways typos can mess up things and the frequency that set some people off.

I am sometimes even a bit baffled.
