This is also the curse of expertise. To most people in tech, uploading a weather dataset for one zip code and making a site that spits out predictions for the weather the next day is trivial.
It would not be an impressive project to people in industry and it would not impress most hiring managers. To quote you, it would be “nothing much”. For most people who aren’t in tech, this project sounds pretty cool and is very much something.
Easy to get lost in the sauce when you spend all day soaking in it.
