Overview

QR Payment Portal

Payments needed to appear instantly, already knowing what the customer intended to do. I built a system that intercepts message-driven data and turns it into a live transaction context — without exposing sensitive details.

Developed a React-based payment interface, intercepted Firebase Cloud Messaging payloads, integrated Stripe, and architected a secure Express backend to handle real-time transactions.

Impact

• Scale: Message-driven payment processing
• Outcome: Secure, context-aware transactions with minimal user friction
