Architecture — Month 0

Loading architecture…

You are Maya's cofounder at Ledgerline — a two-engineer B2B payments startup on Day 1. Two banks have signed. Your first live transfer is in 72 hours.

The next 36 months are eleven decisions. Each one starts with a message in a channel, gives you 3–5 options on the table, and ends with the CTO asking you to defend the call. The choices compound — what you ship at Month 2 you live with at Month 28.

Read #architecture for Maya's open questions. Open About Ledgerline in the header if you don't know who's in the room. Press space when you're ready to begin Month 1.
