Hey @bzzz-coding can you fix the merge conflicts here when you have a chance? Thanks!

Edit:
Wait a second, was this code branched from the old backend? If so we might have to redo it entirely 😕

Hey @LoTerence, yes this was old, but I can redo it and submit a new PR if you want to close this one, or should i wait till we have a better understanding of the user flow?

[LoTerence]

Don't redo it yet - I want a better understanding of the user flow, and using that I think we may have to change the data model.

Right now we have an Opportunities model, and I'm not really understanding the difference between that and Post here.

Let's pause on this PR and keep your work here for future reference.
