I remember when someone like that made a Covid app to show your vaccination status faster and cheaper than Alberta could and the media made him out to be such a hero. One of the hockey teams even required fans to install it to be admitted to the arena.
Well the app consisted of users uploading ID and record of vaccination, then without any check, putting a check mark or something on the screen. All of the uploads were stored in a US server and publicly accessible.
But nothing beats the hero in Ontario that made according to local news stations made fool out of the local government by building stairs in a park for $550 when it was going to cost an outrageous $65k (in the end $10k I think). I think about these stairs[1] whenever someone without experience claims they can make things cheaper.
