Your question is Shipping a Technical Product From Scratch. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
Walk me through a highly technical product you shipped from scratch. I want to understand how you handled ambiguity early on, what trade-offs you made across user value, technical complexity, and speed, and how you decided what to cut or commit to before launch.
