Mine was CS. Build an application that takes in topo data and produces a 3D plot of the output and allows the user to edit the data on the fly.

Remember this was in the late 90s so it was all OpenGL immediate mode and I didn't have a 3D accelerator so it had to run at a reasonable framerate on a 75Mhz CPU. Luckily we didn't have to texture anything, flat shaded polys were fine.

Another project was a web application with a database backend that was basically just IMDB. Of course this was the 90s so it was CGI.

Sadly there was no Git either. CVS was it, but since everybody was on dialup modem and there were not cloud services you could use it didn't work so well. One had to be good at compartmentalizing mostly. One guy would work on one part and someone else would work on a totally different part and integration was always fun.

Not OP, but engineering did a lot of it.
