19:00 React Under Attack: Uncovering Web Vulnerabilities and Securing Your Apps
Speaker: Daniel Coll Leal, Senior Developer Advocate @ Dynatrace

Last month we witnessed the all-time greatest vulnerability in React with a 10/10 CVSS score that allowed anonymous remote code execution. At this point you might be lying awake at night wondering if your app could be compromised again.

Do you want to know how secure the apps you shipped using React really are? Do you know which types of vulnerabilities you might be exposed to when proper security systems are not in place?

In this talk, we'll explore how some major companies were hacked in the past and dive into a demonstration of how our guinea pig web app is hacked to uncover the threats that could easily impact your own projects.

19:30 "Add AI to Our App" — What Does That Actually Mean?
Speaker: Daniel Tamas, Fullstack / React Native Engineer @Phantom 👻

AI is everywhere, and sooner or later, you'll get the (Jira) ticket: "add AI to our app." But what does that mean? Cloud APIs? On-device models? Apple Intelligence?

In this talk, we'll explore the AI options available to React Native developers today - from zero-cost Apple Intelligence to local LLMs. You'll learn when to use local vs. remote AI, how to implement RAG for on-device knowledge bases, and the real challenges of using local models on mobile devices.

19:45: Drinks and networking!

Dynatrace

Dynatrace keeps today’s AI-driven world running smoothly by advancing observability for modern digital businesses. The world relies on software, but what isn’t seen is just how much complexity goes on behind the scenes to make sure everything stays up and running. Most businesses today have extensive digital ecosystems comprising software, data flows, applications, and hybrid cloud environments. As these ecosystems grow in complexity, so do the points of failure.

Outages and glitches resulting in grounded flights or failed financial transactions prove how critical it is that software works as expected, making AI-powered observability an essential capability to ensure digital businesses run smoothly and recover quickly — keeping the world working.

Dynatrace provides businesses with a holistic view of their entire digital ecosystem, removing the burden of operational monitoring and alert management.

By automating these tasks, teams are empowered to transform complexity into their greatest asset and to drive their business forward by focusing on high-impact initiatives, driving topline acceleration, fueling innovation, and delivering experiences customers love.
