Jean Bae · Product design

Designing coherent systems across complex product ecosystems.

I'm a platform and product designer with over a decade in data-heavy systems: programmatic advertising, marketplace recommendations, and monetization at scale. I work from strategy through execution, turning tangled, multi-team problems into products people can actually use.

Mirror · Human–AI collaboration

Understanding human–AI collaboration through conversational data

Most AI products are optimized around discrete tasks. Mirror examines sustained conversational use to understand how memory, context, reflection, and decision-making create value over time.

eBay · Shared item-card capability

Turning the item card into a scalable product capability

The item card was one of eBay's most widely used shared interfaces, supporting recommendations, search, advertising, and other buyer experiences. I helped shape a flexible framework that balanced consistency across the marketplace with the needs of different products and teams.

eBay · Recommendations ecosystem

Building a coherent recommendations ecosystem

Recommendations across the buyer journey had evolved independently, creating inconsistency for customers and fragmentation across teams. I helped define a shared product direction connecting customer relevance, experimentation, and commercial goals.

Approach

How I work through complexity.

Find the system behind the interface

A difficult product problem is rarely confined to one screen. I look at the customer experience alongside the technical architecture, business model, and organizational incentives shaping it.

Connect customer and business value

I use research, behavioral data, experimentation, and commercial context to identify where customer needs and business goals reinforce one another—and where they conflict.

Create direction across teams

I help teams move from fragmented efforts toward shared principles, clearer decisions, and scalable product capabilities.

Let's work on consequential problems together.
