Exchange: digital asset exchange

Turn a rate calculator into a complete product flow that remains clear while currencies, precision, reserves and order states change.

Responsibilities

• Build a reactive send/receive form with instant direction switching.
• Support fixed quotes with a 15-minute window and live floating rates.
• Model currencies, reserves, validators, exchange directions and fees.
• Encrypt payment details and provide order history, cancellation and status tracking.

Role: fullstack developer — product flow, data model, reactive UI and security-sensitive order handling.

I built the exchange on Laravel and Livewire: amounts are stored in atomic units, rate calculations respect each asset precision, and the interface updates without a page reload. Jetstream and Sanctum provide the account foundation, while encrypted addresses and opaque order IDs keep sensitive details out of public URLs.
