Your mission: craft jaw-dropping yet accessible experiences that scale across brands, markets, and devices. What you’ll do Lead strategy → system → flows → UI → motion for 15+ modules across verticals.

Ship micro-interactions and animated feedback with Rive/Lottie that run natively in Flutter. Design ethical gamification loops (progress, streaks, rewards) that drive adherence—no dark patterns. Prototype, test, and validate; ensure WCAG 2.2 compliance and smooth handoff to engineering. Work autonomously with daily WhatsApp updates and a weekly demo/call; build in our Figma.
