Is there codegen framework for business logic?

I have been working on a big project for quite some time now and I am finding myself rewriting and optimizing/duplicating the code quite often and not finishing the damn thing as a whole(this is not just the programmer's strive for perfection but the mostly sheer size of the project). And I am getting really tired of writing the same stuff over and over again. I work with Go which does not have generics but I would not say that is the issue here(I actually do not miss generics, maybe once or twice a year tbh).

In essence, over the years, I grew tired of writing so much code. It's not that I do no like writing code, it's just that I clearly see how much code I need to write in order to implement the business logic. And I'm just tired of it.

So I want to create a code generator that would take my business logic and generate the full implementation out of it so I can truly focus only on that and not the code itself. I have wrote code generators before, usually for event-sourcing stuff and repositories(db), so this is nothing new. But I am after more abstraction, less time spent writing code, more time spend developing the application as a whole. Imagine something like terraform but not for infrastructure but for the code.

So before I attempt to write something on this scale I was wondering if maybe there already is something out there?
