Your interface shouldn’t just play an animation. It should respond. I build interactive Rive experiences and integrate them into web and Flutter applications—from expressive mascots and onboarding flows to data-driven interfaces and playable learning experiences. I’m a Design Engineer who connects animation, interaction logic, and development. I can create the motion, structure its behaviour, and help make it work inside your product—not leave your developers with a beautiful demo they have to rebuild. WHAT I CAN BUILD FOR YOU • Interactive characters with idle, reaction, success and error states • Onboarding, navigation, transitions and UI micro-interactions • Data-bound dashboards and responsive product interfaces • Rive state machines, reusable components and Luau scripting • Flutter integration connecting animation to application events and data • Troubleshooting and refinement of existing Rive systems RELEVANT WORK Alliam — A children’s learning app combining Rive-powered gameplay with Flutter, including interactive challenges, animated feedback and saved learner progress. Formation Engine — An interactive football tactics system built in Rive using scripting and data binding. Mascot systems — Character animation and responsive behaviours created for client projects, with personality carried across multiple interaction states. HOW I WORK We define the behaviours first: what triggers each response, which states matter, and how the animation connects to your application. Then I build and test the experience, with organised assets and clear integration guidance. Core tools: Rive, Flutter, FlutterFlow, Figma, After Effects and Cinema 4D. Have an interface or character that needs to come alive? Send me the design, your app framework, and what you want it to do.
