I've always found juniors to be the most prone to being "clever". Writing complex things for the sake of it. And it's one of the things I think you need to get over if you want to be considered medior/senior. A senior that loves being clever in an actual product is dangerous. Keep that stuff for hobby projects.

At a web agency I used to work at this was definitely a thing we had to teach the juniors. Whatever you built now is going to end up in maintenance with a support team that doesn't have as deep of an understanding of the project. Being overly clever now is going to be a pain in the ass later.

"Keep It Simple, Stupid" is an important skill for a professional.
