19:30: Building a Design System for Web Applications: From Scratch to Continuous Improvement
Speaker: German Quinteros, Senior Frontend Engineer @ Glovo

In this talk, we’ll dive into the essential elements of building a design system for web applications. Starting with why a design system is crucial for consistency, scalability, and efficiency, we’ll explore the key architectural decisions involved in creating a solid foundation.

You'll gain insights into the challenges faced while developing a design system, including component creation, cross-functional collaboration, and maintaining flexibility while ensuring consistency.

Once the system is live, we’ll discuss the importance of ongoing maintenance, how to gather feedback, and strategies for iterative improvement to ensure the system evolves as your product does.

Whether you're starting from scratch or refining an existing system, this talk will provide practical advice and real-world examples for building and maintaining a design system that grows with your web application.

In this talk, we’ll explore how TanStack Router revolutionized our approach to routing in a real-world employer app. From type-safe routes and parallel data loading to state management and performance improvements, we’ll walk through key features that made a difference. You’ll learn about the challenges we faced, our decisions, and the lessons we took away from integrating TanStack Router into our stack.
