What made this system difficult?
Had to keep purchases verifiable (signature integrity, tier handling) while supporting real operations: referrals, admin controls, seller/user flows, email verification, and withdrawal handling.
How did the design respond?
Implemented EIP-191 signature verification in both frontend signing flow and contracts (Factory purchase flow). Built an Express + TypeORM backend with JWT auth + permission middleware and operational route groups (sales/referrals/dashboard/withdrawals/users), plus a protected admin UI for day-2 operations.
