ZurichJS Pro Meetup: H(a)unt the gaps in your Apps

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.

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

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.
