Selected work

Products built around real decisions.

A selection of AI-native experiments, intelligent search experiences and workflow systems—each grounded in user behavior and measurable outcomes.

Case notes

What changed, and why it mattered.

WalletBuddy

From scattered expertise to one conversational entry point.

Problem. Payment teams repeatedly relied on product and engineering specialists for policy questions, data retrieval and incident diagnosis.

Approach. I designed an AI workspace that brings together wallet-domain documentation, query tools and troubleshooting SOPs. A RAG layer grounds answers; the dialogue flow routes harder cases to humans.

Outcome. Routine consultation and diagnosis became self-service, creating a reusable “knowledge → answer → human fallback” operating loop.

Content distribution engine

Making AI content production measurable end to end.

Problem. Manual distribution was slow, content quality varied and user acquisition could not be reliably attributed.

Approach. I connected five modules—tasks, AI-assisted production, channel distribution, monitoring and settlement—and introduced base plus performance incentives.

Outcome. One campaign generated 3,288 pieces, 12.64M impressions and 8,449 effective search referrals; trial acquisition reached 10K new users per week.
