Orchestrating Millions Across the Globe: Reactive Payments at Scale

What happens when 'just integrate Stripe' isn't enough? As platforms grow, payments turn from a simple integration into a complex web of gateways, compliance, and strategy conflicts. This talk is for anyone who's hit scaling pain. I'll walk through the hard lessons from moving millions through fragmented systems, and show how treating payments as orchestration, not a feature, can unlock real growth. No fluff, just the realities of building monetization systems that scale. The best part? I’ll end with a live demo of this running in production on Smallpdf, where we built and shipped our in-house reactive frontend orchestration system in React, now serving tens of millions of users worldwide.
