Context
A financial platform designed for people who hold both fiat and crypto and want one account rather than two disconnected systems.
Problem
International payments, IBAN infrastructure and crypto-fiat switching have very different settlement models. The product had to hide that without lying about it.
Architecture
- Backend and frontend systems designed together from scratch.
- Crypto-fiat switching layer between custody, treasury and payment rails.
- Architecture targeted at global reach across 200 countries.
What I built
- Global payments and international IBAN account flows.
- Currency switching between fiat and cryptocurrencies.
- An NFT-enabled luxury payment card concept combining digital assets with physical payments.
Technology
ReactNode.jsPostgreSQLPayment railsIBAN infrastructureEVM
Hard parts
- Reconciling instant on-chain movement with slower banking settlement.
- Designing for jurisdictional variation without branching the product.
Outcome
A crypto-integrated financial platform designed and led from scratch, architected for global scale.
