Context

Fintech wallet where users hold fiat balances in multiple currencies alongside a separate crypto portfolio (Bitcoin, Ethereum, Solana, and others), send money through four distinct rails (cash pickup, bank transfer, mobile transfer, wallet-to-wallet), and manage a linked card from one dashboard.

Team & Ownership

Built the Flutter frontend and supported backend integration.

Challenges

• —Four distinct transfer rails (cash pickup, bank transfer, mobile transfer, wallet-to-wallet) each needed their own recipient/account fields while still feeling like one consistent Send Money flow.
• —Running fiat balances, a multi-currency wallet, and a separate crypto portfolio side by side without the home screen turning into a wall of numbers.
• —Crypto transfer confirmation flows.

Key Contributions

• —Built the Send Money hub with four transfer methods (Cash Pickup, Bank Transfer, Mobile Transfer, Wallet-to-Wallet), each with its own recipient/account form.
• —Built the crypto tab: portfolio view, buy/sell/deposit/withdraw actions, and a sortable coin list (by price or market cap) across 10+ assets.
• —Built card management and account settings screens.

Key decisions
