Completely agree. If this is a skilled Dev who’s built products like this before and you can build something like this in your afternoons and weekends in like 6 months without LLM tool assistance.

With basic assistance you can definitely cut that time down to 4 months or less easily.

And if this is a full-time project, you can probably get it out the door in 1 to 2 months with llm assistance. (Not vibe coding, two very different things)
