What does it take to build truly performant, scalable web apps in 2025? At this ZurichJS Pro edition, we’re going beyond frameworks and diving into infra that moves the needle: - How to own your deployment pipeline without bloated cloud contracts - How to give every user their own server (yes, really) - How performance connects back to revenue, scale, and payment architecture ZurichJS Pro is our high-caliber meetup format, where we invite expert speakers from beyond Zurich to drop technical insight you won’t find in blog posts. Huge thanks to Stripe and Cloudflare for helping us make this happen.

Amazing Talks at This Event 🎤

A server for every user: Build serverless apps with Durable Objects

🎤 Regular Talk

Serverless architectures offer scalability and cost benefits, but managing application state remains challenging. What if you could spin up a tiny server for every user with the same cost and scalability benefits? A server for every user, in a serverless architecture sounds new, right?
In this talk, I’ll introduce you to Durable Objects and help you understand the new paradigm of building stateful serverless apps. You will learn about the various benefits like low latency, faster database operations, and handling states for your serverless app.

Beyond Translation: The Hard Truths of Payment Localization at Scale

🎤 Regular Talk

Expanding globally doesn’t just mean translating your product. Payments are where growth ambitions meet hard reality. At Smallpdf, we discovered this first-hand while serving millions of users across markets with very different expectations.

In this talk, I’ll walk through the real lessons we learned about payment localization: why adding Alipay was a no-brainer, how currencies and billing defaults shape conversion, and what happens when you try to roll out localized pricing. I’ll also share our experience migrating from Braintree to Stripe, and how payment orchestration became a necessity, not a nice-to-have.

How I Built a Serverless Newsletter Registration System During my Coffee Break

🎤 Regular Talk

True story: I was building an AI agent for Hacker News and realized I needed a way for people to sign up for updates. One coffee break later, I had a complete serverless newsletter registration platform that would allow me to send automated emails.

Join me as I guide you in twenty minutes to create an infrastructure that would be applicable to many use-cases to get information, save them and use that to automate tasks by using AWS' JS SDK.
