About the track
The frontend and mobile landscape is constantly shifting, with new architectures, tooling, and best practices reshaping how teams build for the modern web and mobile platforms. From large-scale UI migrations to Server-Driven UI and Micro-Frontends, developers are tackling the challenges of performance, maintainability, and scalability in innovative ways.
This track will explore real-world lessons from companies optimizing frontend experiences at scale, managing complex design systems, and accelerating mobile development workflows. Whether it's rethinking how UI updates are delivered, navigating technical migrations, or improving speed and efficiency across massive codebases, you'll gain practical insights from engineers solving these problems today.
Join us to discuss the latest frontend and mobile trends, the challenges teams face, and the strategies shaping the next generation of user experiences.

10:35 Windsor (5th Fl.) Session migration So You’ve Decided To Do a Technical Migration Sophie Koonin Web Engineering Lead @Monzo, Writer, Speaker and Web 1.0 Enthusiast It seems like there’s always a hot new library or framework promising great things. But people often forget about the pain and effort required to move from an old technology to a new one. How long will it take? If you finish, will it be worth it? 11:45 Windsor (5th Fl.) Session design systems Scaling the BBC Design System: Tooling, Community, Governance and Gardening Sophie Beaumont Software Engineering Manager @BBC Do you have experience managing or contributing to a Design System that has to support multiple teams, disciplines’ priorities and competing product requirements? Wondering how to meet the long-term goals of the system without getting in the way of your stakeholders’ needs? 13:35 Windsor (5th Fl.) Session architecture Mobile Server-Driven UI at Scale Rafael Ring Senior Staff Software Engineer, Mobile Platform Team @Nubank, 10+ Years Working Full Stack Delivering changes to mobile applications is always painful: dealing with store reviews, users that don't update their apps and multiple concurrent versions being used at the same time. 14:45 Windsor (5th Fl.) Session web performance Speed at Scale: Optimizing the Largest CX Platform Out There Matheus Albuquerque Staff Software Engineer @Medallia, Google Developer Expert in Web Technologies, Programme Committee @React Summit US, Mentor @TechLabs, International Speaker, Technical Reviewer In a world with a wide variety of network connections, any user can have a slow experience, and apps that delight users on fast connections can barely be usable on slow ones. 15:55 Mountbatten (6th Fl.) Session frontend The Ideal Micro-Frontends Platform Luca Mezzalira Director of 50 Cents Media | Former AWS & DAZN | QCon Cohorts Facilitator | O'Reilly Author | International Speaker | Architecture Storyteller Micro-frontends can help organizations scale frontend development, but without the right foundations, they often lead to unnecessary complexity and performance issues. How can you implement them effectively while avoiding common pitfalls?QCon London 2025 is a three day conference for senior software engineers, architects and team leads. An international program committee of working engineers selects every session. Patterns and practices, not products and pitches.
