I built a robot that applies for jobs. The hard part was proving it worked.

The demo was never the problem.

A browser agent that opens a job posting, reads the form, writes your history into it and clicks submit is a weekend of work now. It looks like magic in a screen recording. You can film one this afternoon.

The problem is the sentence you have to say afterwards: it worked.

I spent one full day, eight hours and seventeen minutes, and twelve real applications on real postings, chasing four failures. I landed none of them. Every experiment cost about fifty-six minutes, because most of that was waiting for a deploy to reach the machines that run the applications before the test could even begin.

Three separate fixes to one small function shipped fifty-five minutes apart, then fifty-four minutes apart. All three were properties of the same HTML element, and all three were findable in a single pass with a browser open in front of me.
