The work
Telecom integration. Direct integration with telecom provider APIs to issue eSIMs in real time. When a customer completes a purchase, the system provisions their eSIM, generates the activation QR code, and delivers it instantly. Failed provisioning triggers automatic retries and alerts.
Worldpay payment processing. International payments with multiple currencies, fraud checks, and PCI compliance requirements. Full payment lifecycle: charges, refunds, failed payment recovery, and webhook processing for async confirmations.
Production deployment. Infrastructure setup and deployment pipeline. The platform runs reliably under real customer traffic with monitoring, error tracking, and the operational tooling needed for a consumer-facing product.
Multi-country support. Different countries, different telecom partners, different data plans, different pricing. Adding a new country is a configuration change, not a development project.
