Donation Platform

Built a production-grade charity and fundraising platform from the ground up — backend API, admin panel, and public-facing website — as three independently deployable applications. The platform enables donors to browse charitable appeals, make secure payments through Stripe, PayPal, and SSLCommerz, create personal fundraising campaigns, attend events, and track their donation history. The admin panel provides content management, analytics dashboards, invoice generation, and full site configuration. Real-time features powered by Socket.IO deliver live donation feeds and instant payment status updates.

Challenges & Solutions

  • Integrated three independent payment gateways (Stripe, PayPal, SSLCommerz) into a unified checkout flow with idempotent webhook handlers
  • Designed a real-time architecture with Socket.IO namespaces — public live donation feed and authenticated admin notifications
  • Built a fully CMS-driven frontend where all homepage sections are dynamically rendered from backend configuration, with graceful fallback when the API is unavailable
  • Implemented automatic token refresh with request queuing in the admin panel to prevent race conditions during concurrent API calls
