Flutter Engineer at Holafly | Flutter & Dart GDE | WTM Ambassador

I'm a Software Engineer from Montevideo, Uruguay, passionate about building thoughtful mobile experiences and empowering the dev community. I work as a Flutter Engineer at Holafly e-SIM, and I love sharing my learnings through talks at events like FlutterConf LATAM and FlutterCon EU. In 2025, I became the first woman Flutter & Dart GDE in LATAM, and at present, the only active one across the Americas. As a Women Techmakers Ambassador and co-organizer of FlutterConf LATAM, I love bringing people together to grow and learn. When I’m not coding, you’ll find me out walking with my dog or diving into personal growth content.
Don’t Break the Brand: Maintaining a Design System in Flutter
Building reusable widgets in Flutter is easy. Building a design system that scales and stays consistent over time is not.
As applications grow, design systems often turn into “widget dumping grounds”: inconsistent APIs, duplicated styles, and components that slowly drift away from the original design intent. Without clear boundaries, a solid theming foundation, and proper validation workflows, even well-intentioned systems become hard to use and harder to trust.
Drawing from our experience building and evolving the design system behind the Holafly app, we’ll share real-world challenges, trade-offs, and lessons learned while scaling a production UI system.
Whether you’re starting a design system from scratch or trying to regain control of an existing one, joining us in this talk will give you practical tools to ensure your code remains a source of truth rather than a source of frustration.
