Overview
Build and own the backend platform for a non custodial crypto payment product: core APIs, merchant accounts, and transaction services using Node.js and TypeScript.
Develop the point of sale (POS) software interface: amount entry in AED, QR code generation, and a two-state payment display (instant on chain “Payment Confirmed” and same day “AED Settled”).
Build the merchant dashboard: transaction history, settlement status, analytics, and wallet/settings management.
Develop a blockchain event listener that reads on chain payment events and updates the POS and dashboard in real time (the bridge between the smart contract and the user interface).
Integrate a licensed third party OTC provider for AED settlement via API.
Integrate transaction screening tools (e.g.
Chainalysis, Scorechain) into the payment and onboarding flow.
Own infrastructure and security: AWS, PostgreSQL, Redis, webhooks, CI/CD, authentication, and audit logging
