Vertical Fintech Mobile
avelikiy/great_ctoDomain-knowledge pack for money on a phone — wallets, payments, custody and signing, transaction lifecycle, KYC/AML gates, and offline reconciliation. The rules that separate a payments app from a CRUD app with a currency symbol: a balance is a claim about a server, an idempotency key must outlive the process that made it, keys never enter JavaScript memory, and a device clock may not order financial events. Applied by architect/pm/design-advisor when specing a mobile product that moves money, and by mobile-app-builder while implementing it.
