Name: ZurichJS Pro Meetup: H(a)unt the gaps in your Apps
Start: 2025-10-28T18:00:00+01:00

Every web app has ghosts lurking in the shadows — hidden performance drains, invisible vulnerabilities, and subtle bugs waiting to strike.

This October, we’ll shine a light on the dark corners of modern web development:

* How to exorcise buffering and heavy data costs with smarter video optimization.
* How attackers slip through cracks in your app’s defenses — and how to stop them.
* How to tame unruly JSON with schemas that keep your data (and your sanity) intact.

Join us for an evening of code, demos, and a few scares, as we uncover the missing pieces that haunt your apps.

**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.

🎟️ **Still free to attend.**
Bring your crew. Share your referral code from your [ZurichJS account profile page](https://zurichjs.com/?signup=true). Earn points toward exclusive goodies and perks.

🏢 Got a venue idea? We love rotating locations to showcase Zurich’s tech ecosystem. Reach out, we’re always scouting fresh spots for our upcoming events.

**Want an even deeper dive?**
Join us a couple of hours before the meetup, we're running a workshop on
👉 [Observability in Action: Hands-On with Dynatrace](https://zurichjs.com/workshops/observability-dynatrace)

Learn to master modern observability with hands-on experience using Dynatrace. This workshop will teach you the three pillars of observability - metrics, logs, and traces - through practical exercises with the AstroShop application.

You'll discover how to build alerting that reduces noise, implement cost-effective data ingestion strategies, and use distributed tracing as a debugging superpower. By the end, you'll understand how to create a mature observability setup that provides actionable insights for your applications.

**Spots are limited**, so grab your seat soon.

Bringing your team? Email **hello@zurichjs.com** and we’ll help simplify the process.
