"Can we set up this automation? A report gets auto-generated daily, and emailed to two people."

Friday afternoon. Fifteen-minute job, sure, no problem.

Then we started asking questions. And discovered: a single report per project. Many projects. Several different forms and report templates. Dynamic filtering, depending on when each project was last updated. A lot of data, and therefore pagination. Async jobs, because the report isn't ready the moment it's requested. And large files that crash the email service.

Fifteen minutes became most of a day.

You need to have a bit of a detective in you. "Send a report to two people" is almost never just about sending a report to two people.

What's the biggest build you've seen hiding in a tiny request?
