We all know and have different and loosely held opinions about designers coding. But what about the opposite?

Personally I've had uncomfortable interactions trying to navigate and
performing critical tasks in both school and tax paying system.

At the time there feel like Norman Doors, specially a time when I was asked to create a really strong password in order to protect critical information. After a form was submitted, no feedback was presented to the user. Upon further inspection a realized that a fetch request was made to the server and it has a ~5 second latency. If things go wrong, which they did, no feedback was presented to the user. It was really, really painful.

When you hire a developer, you don't expect her to design, however some UX or UI design is always appreciated. What's your take?
