Sounds about right for someone who ships fast and iterates. 54 days for a v0 that probably needs refactoring isn't that crazy if the dev has a real DB background. We've all seen open source projects drag on for 3 years without shipping anything, that's not necessarily better
shipping fast matters a lot less than shipping something you actually understand. 200k lines in a week means nobody knows what's in there, including the author. that's not a codebase, it's a liability
