LeedsJs

Join us this May for a special Leeds JS event focused entirely on web performance — one of the most critical (and often overlooked) aspects of modern web development.
We’re thrilled to welcome Harry Roberts (csswizardry.com), an award-winning web performance consultant and international speaker. Harry has worked with organisations like Google, the BBC, and the Financial Times to diagnose and fix real-world performance issues, helping teams build faster, more efficient websites.

Expect deep, practical insights into:

Diagnosing real-world performance bottlenecks
Building faster, more resilient frontends
Making performance a core part of your engineering culture

We’ll also be joined by a Developer Relations expert from Leaning Technologies, bringing a unique perspective on high-performance web apps, WebAssembly, and pushing the limits of what’s possible in the browser.

⚡ Whether you’re a frontend engineer, full-stack dev, or just performance-curious, this session will give you actionable techniques you can apply immediately.
