🗣️ Talks

➡️ Modernizing Your React App: Compiler, useEffectEvent, Activity & Friends
React has changed a lot in the last year: React 19, 19.1 and now 19.2 brought a stable React Compiler, new hooks like useEffectEvent, the \ API, and better SSR primitives such as Partial Pre-rendering. And more
In this talk we’ll take a demo React app that’s full of effects, memoization and “old school” patterns, and modernize it step by step.

➡️ A Triplestore-Powered BaaS: Real-Time Collaboration Without the Backend
Backend-as-a-Service platforms promise simplicity, but often lock developers into complex APIs authorization rules. What if your frontend could directly manage data, authorization, and collaboration - without domain-specific backend code?
In this talk, Oliver shares how he built a triplestore-based BaaS to power real-time collaboration in his side project MonsterWriter, and how the approach grew into an independent open-source project. We’ll see how LinkedRecords.com enables fine-grained authorization, simplifies real-time collaboration, and supports a Bring Your Own Backend model that gives organizations more control over their data and vendor relationships. It is also shown how global state management becomes a lot easier in React apps.

➡️ Building Cross-Platform Agentic UI at Superhuman
Recently, Superhuman (formerly Grammarly) launched Superhuman Go, an AI assistant that works alongside you on every platform. To build it, we needed a scalable solution that supports an unlimited number of agents that dynamically shapes the user interface and looks similar across all supported desktop and mobile platforms. Join me to find out how we discovered solutions for this innovative new product.
