Draw the boxes, name the boundaries, define the contracts. Then write the implementation — not the other way around.

Zod at the boundary, TypeScript through the middle, Prisma at the floor. Errors caught at compile time, not in production.

Every meaningful decision lives in the code, not in someone's head. Future-me — and future-teammates — get to read the why.

Production data beats architectural debate. Get the v1 in front of real users, instrument it, and let the metrics drive v2.
