BETWEEN WORLDS

I work between the human side of technology and the technical side of human needs.

Through human insight, storytelling, data, and AI-native building, I explore how better products, stories, and strategies emerge when we understand both.

BETWEEN
WORLDS

is not just about having a cross-disciplinary background. It is the way I have learned to see and work.

I grew up in China, studied communication in the UK, and now study Communication Data Science in Los Angeles. Across these shifts, I have learned to move between cultures, disciplines, and ways of thinking: from human stories to data, from marketing language to product logic, from AI systems to the people who need to understand and use them.

My work starts from people. I care about what they feel, what they struggle to explain, and what they need before they can fully name it. But I also want to understand what technology can actually do: where AI helps, where it fails, and how technical possibility can become something useful, trustworthy, and human.

That is the space I am building toward: between human understanding and technical possibility.

That is the space I am building toward:

HUMAN UNDERSTANDING

TECHNICAL POSSIBILITY

WHAT I DO

I build from both sides: human understanding and technical possibility.

01

BUILD AI-NATIVE PROTOTYPES

I turn real workflow pain points into testable AI product experiences, using tools like Claude, Cursor, Replit, and emerging AI front-end workflows to prototype fast and iterate.

02

SHAPE PRODUCT AND GTM NARRATIVES

I help ideas find the right audience, message, and moment — from zero-to-one campaigns to early-stage entertainment strategy and product positioning.

03

READ PEOPLE, CULTURE, AND SYSTEMS

I combine communication, user research, data, and cultural observation to understand what people need, what they respond to, and where technology can actually help.

FEATURED
WORK

Three proof cases across AI product building, GTM, and strategy.

01 / Triage · Sep–Dec 2025

Triage

Zero-to-one AI Prototype / User Validation

AI Product Builder · Solo Project

I identified information overload as a cognitive burden in email workflows, then built and validated an AI Gmail add-on that turns inbox noise into clear priorities and next actions.

Core Insight
Email overload is not just a reading problem. It is a decision problem: users need to know what is urgent, what needs action, and what can wait.
Proves
AI-native building / product thinking / user pain identification / early-stage execution
Proof
10-user beta · F1=0.90 task extraction · ~90% faster decision clarity · 80%+ daily-use intent

Marketing Associate

What I Did
Designed AI evaluation workflows using tiered prompt sets, multi-turn scenarios, and human + LLM-as-judge rubrics. Translated abstract AI risk categories into structured evaluation criteria for an enterprise AI Trust Index and public safety leaderboard.
Takeaway
AI systems do not only fail technically. They fail in interaction: when persuasion, ambiguity, or context shifts the model's behavior.

News Widget

Product Researcher · RJI Competition Finalist

Sep 2024–Jan 2025

VISUAL WORK

Creative Practice / Visual Portfolio

my whole life

Outside of my professional work, I am a Rednote content creator and a freelance photographer.

I started learning drawing when I was three, and photography became one of the main ways I observe people, places, and cultural memory — and later, a way to build audiences around visual storytelling on social media.

Let's work together!

I'm interested in the space where AI products become clear, useful, and ready for the market.

I bring product sense, GTM thinking, and AI-native building habits to help unclear ideas become understandable products, sharper narratives, and real user signals.

If your team needs someone between product, marketing, and growth,
Let's talk.
