Caching, Payloads, and Other Dark Arts: A Frontend Engineer’s Journey
What do you do when your frontend performance crumbles, but you have zero control over the backend? This was the reality we faced while building a fintech payments dashboard. Massive payloads, strict compliance, and an unchangeable API were slowing operators down and wrecking workflows.In this talk, I’ll walk through our real-world quest to rescue the user experience without touching the backend. You’ll see how we profiled true bottlenecks, built a Backend-for-Frontend layer to reshape data for the UI, managed financial data caching strategies, and balanced performance against several constraints.Expect live demos, battle-tested patterns, and hard-earned lessons for shipping resilient, user-centric frontends, even when the backend isn’t on your side.

From Fragile to Future-Proof: Solving Web Monetization Chaos with Payment Systems That Scale
When your platforms expands into markets beyond your own and has ever growing monetization needs, ‘just integrate Stripe’ is easier said than done, here’s how looking at payments as technical orchestration rather than just a feature solves growth bottlenecks.At scale, businesses drown in fragmented payment gateways, regulatory minefields, and conflicting monetization strategies. With a plethora of payment APIs on the market, balancing cost, compliance, features, and conversion rates becomes a challenge, as there comes a point where the drawbacks of having one provider start to become a limiting factor. The catch? No playbook exists. This talk shares hard-won lessons from integrating several payment methods, gateways and tier one banks, surviving millions of dollars in transactions, and designing architectures that scale without sacrificing agility.
