PRIMARY SYSTEMS

CryptoPay — Crypto Payment Gateway Next.js · TypeScript · REST
crypto-pay-iota.vercel.app github.com/Andrii-888/crypto-pay
• Designed a PSP-style payment flow: server-side invoice creation, lifecycle and expiration logic, polling-based
status updates, webhook delivery patterns and AML hooks.
• Implemented a Stripe-like hosted payment page for USDT / USDC checkout, with multi-method UI and clear
handling of confirmations, delays and errors.
• Designed as a PSP-like end-to-end payment flow without custody of funds.

PSP Dashboard — Operations & Compliance Panel Next.js · TypeScript · NestJS API
psp-dashboard-ochre.vercel.app github.com/Andrii-888/psp-dashboard
• Built the operator-facing UI for a crypto payment processor, with full visibility across the invoice lifecycle,
sanctions screening and risk decisions.
• Includes backend-driven state management via NestJS API (psp-core) — invoice lifecycle, webhook retries,
AML hooks and blockchain transaction tracking.
• Implemented amount-tiered risk policies, operator actions (approve / hold / reject) and an audit trail intended for
compliance review workflows.
