Overview

At Vitaon, I was brought in as the first product designer to help launch a new healthtech service: an AI-powered quiz that recommends personalized supplement plans based on a user's health goals and lifestyle. With no product or visual direction in place, I took ownership of the entire design process — from system architecture and brand UI to high-fidelity prototypes and live web implementation.

Challenge

Vitaon’s vision was clear: make the overwhelming supplement market easier to navigate through personalization. The challenge was to design a lightweight, trustworthy, and conversion-optimized experience that collects sensitive health data through a quiz, processes it via AI, and delivers clear, helpful supplement recommendations.

Goals

• Design a smooth and engaging onboarding experience to collect user health data
   
• Make the quiz feel personal, fast, and credible
   
• Communicate AI-driven results with transparency and clarity
   
• Build a design system to streamline UI decisions and future growth
   
• Create a live, production-ready web app experience — built directly by design
   

My Contributions

• Product Strategy: Collaborated with the founders to define the core user journey from quiz to recommendation, including user motivations, data points, and value exchange
   
• UX Design: Designed the complete flow — onboarding, quiz, AI-generated results, and supplement plan presentation — with attention to accessibility and simplicity
   
• System Design: Built Vitaon’s first design system in Figma, covering layout, typography, forms, components, and responsive behavior
   
• Brand Expression: Created a clean, modern visual style to balance wellness, intelligence, and credibility, avoiding cliché “natural” health tropes
    
• Conversion Focus: Prioritized clear CTAs, frictionless quiz progress, and reassuring feedback for higher user completion and conversion
   
    

Outcome

I helped turn Vitaon’s concept into a real product, ready for public launch. As the sole designer, I delivered both the user-facing web app and the foundational design system to support future features like user dashboards, subscription flows, and deeper AI explanations. The project demonstrated my ability to operate independently in early-stage environments while maintaining a user-first, system-driven approach.
