Led end-to-end UX for PromoPro, a greenfield B2B promotion platform on Amazon Vendor Central for Tier 1 vendors. As Design Lead and team lead, I owned the experience across Planning, Execution, Calendar, Campaigns, and Analytics, while creating design principles and reusable patterns that other designers could apply when supporting the product.

I facilitated peer design reviews, aligned work across designers, and helped the team deliver focused design sprints to meet aggressive product goals. I also stepped into a PM role to shape the Analytics feature, proposing a GenAI-powered insight narrative experience with upsell opportunities and A/B testing against a data-only control.

PromoPro launched in phases from 2025 to 2026, was adopted by 10 Tier 1 vendors including Coca-Cola, and contributed to a projected ¥247M annual revenue opportunity.
