Set your WebExpo 2025 event watchers, May 28-30 is approaching fast. We’re bringing together leading experts in front-end and back-end development to share insights, strategies, and practical knowledge. Discover the latest trends, refine your skills, and connect with fellow developers passionate about building cutting-edge web applications.
It’s time to query the speaker lineup for WebExpo’s 7 must-attend dev talks of 2025. 
Smarter UIs, stronger web
Generative User Interfaces (GenUI) are transforming UI design, enabling applications to adapt dynamically with AI rather than relying on static layouts. This shift allows interfaces to evolve in real time, creating more intuitive and personalised user experiences. In his talk From GenAI to GenUI – Codify Your UI on the Fly, Tejas Kumar will explore how developers can harness AI to generate UI components on the fly, making front-end development more efficient and adaptive.
Keeping up with this evolution also means understanding the ever-growing web platform and its capabilities. Mariko Kosaka will guide developers through the Web Platform Baseline project, a practical approach to tracking which features are interoperable across browsers today. No more guessing if an API is safe to use; Baseline helps teams make informed decisions and focus on building great products with the best tools available.
Dependency management and code maintainability
Modern JavaScript projects are growing in complexity, often leading to dependency chaos that slows development and makes maintenance a nightmare. Carmen Huidobro will tackle this challenge in her talk, Untangling Your Dependencies: A Pattern for a Well-Knit JavaScript Project, where she’ll share strategies for structuring projects more effectively, improving code manageability, and avoiding the common traps of messy codebases.
When it comes to clearing up clutter, Krasimir Tsonev is taking a step back, a long way back. With 20+ years of experience in web development, he’ll revisit the tools, languages, and design principles that shaped the web, drawing lessons that still apply today. Returning after his extremely popular WebExpo 2024 talk, we know this will be a mix of serious and silly. But that’s not all 
Krasimir will also be delivering a (slightly more serious) full-day “React in patterns” workshop, where developers will learn advanced techniques for building scalable, maintainable React applications while gaining a deeper understanding of React’s core concepts.
And if you’re ready to push your React skills even further, Ariel Shulman will break down React’s concurrent model from the ground up. You’ll learn how concurrency works in React, what problems it solves, and how server-side rendering (SSR) and streaming components fit into the picture.
From secure code to seamless transactions
Mastering security is no longer optional for modern full-stack developers. Vojtěch Vondra will explore how security vulnerabilities impact every layer of an application and why developers (not just security teams) must take charge. He’ll share practical ways to spot real threats, avoid common mistakes, and integrate robust security measures. With AI becoming a double-edged sword in cybersecurity, expect insights on how to use it to your advantage rather than fall victim to it.
Seamless and secure transactions are just as crucial. Alvaro Duran Barata will dive into the increasing demand for payment applications, showing how to leverage Python to build in-house solutions quickly and effectively. His talk will highlight best practices and real-world obstacles faced when processing payments at scale.
