• Visualising design ideas using storyboards, mock-ups, low-to-hi fidelity prototypes and AI-assisted design tools to rapidly generate, explore and refine concepts.
• Representing the UX function across various teams and products
• Facilitating design workshops with the various teams to collaborate on initial ideas and wireframes.
• Implementing functional ideas, use cases, user stories into prototypes for user testing and development.
