So I've been vibe coding with claude for a few months and actually got a decent working mvp for a technician helper app (I work in appliance repair). Sometimes my mind races with so many new ideas that I don't know how to handle haha. It's kept me up at night before because in one way I can see a path forward to so many of my ideas if I can implement a good system and make ai work for me. I want to know how you guys plan for and implement large scale coding projects? I think my most ambitious was creating a full field service suite with invoicing and dispatching and "smart parts" and some other stuff. Building from the ground up with AI in mind. But I feel like this is too big, even chunked down into smaller portions. I've taught myself a little bit of coding, but nothing on the scale for my ambition, and I honestly don't have time to do that (in a reasonable amount of time in my mind anyway haha). How do you decide what's feasible?
