Overview

As Principal Product Designer, I led the design of Merch One, Walmart's unified merchandising platform that brought together key business functions including pricing, inventory, assortment, financials, and space management into a single experience. Designed to replace fragmented tools and workflows, Merch One gave merchants a centralized place to understand their business, make informed decisions, and take action more efficiently. The platform was built to support multiple domain teams, each independently developing and maintaining their own applications while contributing to a connected user experience.

Opportunity

Merchants couldn't act fast enough on in-season issues

Merchants struggled to respond quickly to in-season business issues because critical data was fragmented across multiple tools and sources. Identifying, prioritizing, and root-causing problems required slow, manual workflows with no clear path to action or visibility into whether decisions and interventions were effective.

Solution

A single platform with shared services

Merch One unified independently built micro-apps into a single seamless product experience, held together by a shared LDM design system. Delivered across two phases, the platform evolved from a consolidated navigation to a full redesign with a personalized dashboard, a top nav for tool switching, and a dedicated in-tool navigation for deeper workflows.

Phase 1: Universal Navigation:

Centralized location to navigate to the core tools that merchants use on a day-to-day basis

Phase 2: Site Redesign

Phase 2 introduced a personalized landing page dashboard and a full site redesign. I partnered with product designers to streamline UX workflows across the platform, collaborated with Walmart's Living Design System team, led a Sketch to Figma migration, and established governance frameworks including design syncs and office hours to keep the system cohesive as it scaled.

Quotes

Merchant Partner

“Opportunities are now surfaced with data-backed recommendations, and I can see platform health in real time. It's completely changed how our distributed teams operate and how confident we feel acting on what we're seeing."
