Rive Animator | Flutter | Motion Design | UI/UX Animation | 3D

I create interactive UI animations in Rive and Flutter for mobile apps, SaaS products, onboarding flows, dashboards, and modern digital experiences. Unlike Lottie or GIF-based motion, Rive supports responsive animation systems with real-time logic and interactivity built into the interface directly. I use Rive to design interfaces that respond dynamically to user input, application state, cursor movement, and live data in real time. My focus is on production-ready Rive animation systems that developers can easily integrate into real applications. Beyond aesthetic appeal, I develop responsive motion systems that are suitable for actual product environments, ensure good runtime performance, and support scalable UI behavior. Core Technologies • Rive (rive.app) • Flutter & FlutterFlow • Figma • After Effects • Cinema 4D • Lottie Rive Animation & UI Motion Services • Interactive Rive animations for mobile and web apps • Rive UI animation and micro-interactions • Interactive onboarding systems in Rive • Runtime-driven UI animation systems • Responsive dashboard animation in Rive • Interactive mascot systems and character animation • Logic-driven product animation workflows • Flutter-ready Rive integration workflows • Lightweight animation systems optimized for production apps • Interactive app transitions and responsive UI motion • Data-driven animation systems in Rive • Scroll-based storytelling and immersive UI interactions • Responsive animation behavior linked to runtime state and user interaction • Developer-ready Rive assets with structured logic and scalable workflows Why Teams Use Rive & Flutter Rive enables modern products to shift from passive animation to lightweight, responsive, interactive user experiences across the Web, iOS, Android, and Desktop. I assist teams in creating interfaces that feel dynamic, polished, and efficient without relying on heavy video-based workflows. My approach centers on clean integration, good runtime performance, responsive behavior, and animation designs that developers can easily use in production settings. Performance & Integration Focus • Lightweight Rive assets with quick load times • Lower memory usage compared to video-heavy workflows • Consistent experience across Flutter and modern frontend environments • Well-structured animation systems that support scalability and maintenance • Clear developer handoff and integration-ready Rive workflows From interactive mascots and onboarding flows to dashboards and responsive app interfaces, I design Rive experiences meant for real-world production use. Let’s create something interactive.
