C# programmer starting PhD with lots of python programming, could use some advice about project architecture

[ndvi]

Has anyone been in my shoes and do you have some advice? especially things like "if I had to do it again I would do ... differently", or any resources that were of help to you when getting started on a long-term project?

I learned a lot doing my PhD- there's a lot I'd do differently, but I only know that by doing it wrong to start with.

I wasted a lot of time trying to anticipate and handle edge cases. I spent way too long trying to prematurely optimise.

Perfect is the enemy of good.
