I hear this pretty often, typically from very talented developers who have never shipped traditional commercial software as a product (which is definitely a dying breed). I don't care how good you are, you shipped a PoC in a week, not a product. It's great that your self reflection has identified what you're both good at and want to do, but a lot happens outside of writing code to create a product and this can take a long time. I've built a few in my career where I had involvement in the entire process, and typically the difference between when we're "done coding" to when the product is completed is 4x. I'm slow so maybe you can get this down to 3x, but I'm not convinced.
If I had one dream for software development the field and craft it's that we would build less, better.
