The first dev project, like real dev project, I participated in was a school one and it was double.
The class was meant to make us learn about the software's life cycle, so the teacher wanted us to develop a simple, yet complicated, thing: a Web platform to help tutors send/refer students to the university services (psychologist, nutriologist, etc) and to keep track of them visits.
We all agreed on it being easy.
Boy were we so wrong.
I was appointed as dev leader as well as some others (I was the programming leader, the other ones were the DB guy and the security guy) and as such I was in charge of the technology used (well, now we all know that the client is the one in charge of that as well as the designer) and I chose Django because we had some experience with it. We used it for the two projects the teacher asked us to do (the second one was to find a little shop and develop something for it, obviously with the permission and all that), but in the second one I decided to use React on top of Djangl, which ended being a really good combination tho.
So, in the first project, the other ones (all the classroom) started to discuss and decided to use some other stuff like unnecessary carousel for images, unnecessary functions, they created mock ups for stuff that was never there to begin with, etc. It was really awful, we had meetings with the client (the teacher) with updates on the project, and in not a single one he was satisfied with the results. But still, we continued with the path the majority chose and it was the worst: deadlines were not met, team members just vanished until the end of the semester, one guy broke his leg (and was a dev leader) and never said a word not did anything about the project. At the end, we presented literal garbage, the UI was awful, its colors were so ugly because we had to use the university official colors, the functionality was not there, there literally was a calendar to make appointments for the services (when did the client ask for that? No one knows), but hey, you could add services and their data to it, was it what the client wanted? Of course not! What do you think we are? Devs?
Suffice to say that, although we passed with good grades, the project and the team was shit (and I'm counting me in)
The good part is that the second project was finished by me and it looked really good, yet it didn't matter, the first project was supposed to be used by the university, but that thing was unusable.
Then, in the subsequent vacations I tried to make pretty and functional/usable, yet I failed because I had a deadline for another thing I had to do, but hey, the login screen looked amazing!
