I build AI products from human need to a shipped system.

Graded Chinese listening from real stories, with synced pinyin and translation. Web, iOS, and podcasts.

• Shipped the learning loop so stories, audio, and vocabulary match each learner's HSK level.
• Built the web and iOS product people use to listen, look up words, and come back the next day.

An AI coach for amateur athletes. It reads their training data and writes plans they can understand and change. Chinese beta.

• I own the agent: tools over activity data, a coach that proposes and revises plans, and the evaluation harness that checks those suggestions.
• I also built most of the product the agent sits in: activity import, planning, teams, and the workspace.

Let people and external agents create, iterate, and deploy applications through an interface they can trust.

• Built Atoms CLI 0→1 as a control plane for Atoms’ agent workflows: creating, inspecting, validating, and deploying apps.
• Shaped the platform across product strategy, interaction design, and engineering, documented through 15 RFCs and PRDs.

A cross-platform timer that makes breaks harder to skip while keeping its rules transparent.

• Designed a work-and-rest product for Windows, macOS, and Linux around transparent rules and explicit user control.
• Grew it over six years into a multilingual open-source product with an international contributor community.

An AI-assisted paper-cutting tool that helps creators work with cultural symbolism, not shape alone.

• Designed a system that connects visual form with cultural meaning, then evaluated it in a 16-person study.
• Published the work as a full paper at ACM CHI 2025.

A computer-vision defect-detection system that learned from normal production samples and ran in real time on low-cost edge hardware.

• Co-led a deployed quality-inspection system, pairing normal-only anomaly detection with a dashboard shaped by factory-floor observation.
• Optimized the vision pipeline for real-time inference on a ~$40 edge unit, contributing to a 10% quality improvement.
