Type-Safe Registration & Payment Engine

Type-Safe Registration & Payment Engine (React, TypeScript, Paystack) I engineered a highly secure, automated registration and payment storefront designed for industrial training programs.

Business Value Delivered:

Zero Administrative Overhead: Built an event-driven pipeline using Supabase webhooks and Make.com to instantly email physical admission letters the millisecond a payment clears.

Fintech-Grade Security: Integrated the Paystack API for real-time transactions, paired with a strict TypeScript architecture to mathematically eliminate data-handling crashes and protect financial data.

Optimized User Experience: Implemented Zustand for lightning-fast global state management, ensuring a seamless, zero-data-loss journey from the landing page to the checkout gateway.

Secure Internal Operations: Developed a protected admin portal for venue staff to verify student registration tokens and manage live check-ins securely.
