ZurichJS Pro: Flare up your Performance

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.

#### Agenda:

• 17:30 – Doors open
• 18:20 - 18:35 – Settling in & Intro
• 18:40 - 19:00 – Stormkit: Build, Deploy, and Own Your Cloud ~ Savas Vedova
  In this talk, we’ll dive into simplifying cloud deployments with Stormkit, tackling the challenges of complex setups and rigid hosting platforms. We’ll start by exploring how Stormkit enables deployment on a single VPS in just minutes, perfect for developers seeking efficiency.
  Then, we’ll demonstrate how Stormkit seamlessly integrates with private cloud resources like AWS lambdas and S3, offering control and flexibility. Through a hands-on demo, you’ll see how to build, deploy, and own your cloud infrastructure with ease. Join me to learn how Stormkit empowers to streamline workflows and take charge of your hosting!
• 19:10 - 19:30 – A server for every user: Build serverless apps with Durable Objects ~ Harshil Agrawal
  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.
• 19:40 - 20:00 - Talk 3 TBD
• 20:00 onwards – Network with fellow JavaScripters
