Deliver a practical and insightful session on optimizing web app performance, focusing on real-world techniques to enhance speed, availability, and user satisfaction. Explore topics such as caching, lazy loading, client-side rendering, and leveraging modern tools like Dynatrace and Chrome Lighthouse. Learn how to scale architectures, prevent thread blockers, and align with Core Web Vitals to deliver faster, more efficient web experiences.

This session covers a structured approach to system design interviews, focusing on scalability, best practices, and trade-offs. Learn how to break down problems, communicate effectively, and tackle common pitfalls. We’ll also explore key non-technical skills and tricky interview questions to help you excel under pressure.

Chat interfaces are everywhere, but what challenges are there to overcome to create a truly joyful user experience? In this talk, we’ll explore the key problems and solutions across the entire stack: from the tools you can give your agent to better respond to real human behaviour, to the underlying infrastructure and optimisations required to handle client disconnects, cancellations, and multi-device usage gracefully.

Performant Architecture for a Fast Gen AI User Experience

More and more developers are being asked to build Generative AI experiences into their web applications everywhere. However, the user's experience with Generative AI can sometimes be slow and frustrating. It’s been years since we would gladly wait over 10 seconds for a response to anything online. As AI processing gets faster, there are new limiting factors that could be negatively affecting your AI user experience.

In this talk, we will cover different ways to minimise laggy experiences in web applications when interacting with third-party Generative AI tools. We’ll be using a practical demonstration to show how you can reduce latency as we build one of my favourite sci fi gadgets, the babel fish.
