Master's student at Peking University · Class of 2027
Start with a human need. Build an answer that works in real life.
I care about why people need something, and how it can become part of their lives. I form a judgment, build something people can try or use, and revise it when reality offers new evidence.
SELECTED WORK / Made real. See for yourself.
APP 01 / iOS APP · Organize lecture photos
Lecture Asset
Give the lecture to AI. Get your photo library back.
Lecture photos linger in the camera roll
Submitted for App Review; not publicly released yet
The need
A lecture leaves dozens of slide photos in your camera roll. You rarely revisit them, but you hesitate to delete them. Passing them to an AI for a summary takes more organizing than it should.
The response
Lecture Asset orders selected photos by capture time and creates a PDF for people to read, plus a ZIP package for an external AI. The package contains an OCR index, instructions for the AI, and the original JPGs. Once the lecture materials are organized and saved, you can clear the photos from your camera roll.
APP 02 / iOS APP · Gentle time reminders
Everwhile
Feel time passing. That's all.
Feel time passing
Preparing for store release; not publicly released yet
The need
It's easy to lose track of time while watching videos or reading a novel. Everwhile is meant to help you notice time passing, even while you're immersed in something.
The response
Choose the apps you want to keep an eye on, set a reminder interval, and receive gentle reminders as you use them. Later, Today shows where your time went. You decide whether to continue, pause, or leave.
01 / AI SOCIAL · Interactive prototype
QQ Lingxi
From understanding a person to finding the people and groups that fit.
02 / HARDWARE · Working prototype
Automated Flow Solid-Phase Peptide Synthesis Platform
Turning a synthesis workflow into a machine that runs it automatically.
BEHIND THE WORK
What matters to me behind the work.
I'm curious about why people choose what they choose.
Why do people need something? Why would they pay for it? What actually becomes part of their lives? These are the questions that draw me to products and business.
I want to make things that add a little happiness to everyday life.
A reassuring call, an ordinary moment seen by someone who cares, or a product that simply feels better to use. I hope life is a little better even after someone puts the product down.
Think it through, then let reality answer.
Clarify the goal and constraints, test the crucial questions on a small scale, then make something people can experience or operate. When new evidence arrives, update the judgment.
MORE PRACTICE
Other places where I learned to make things work.
Organic Chemistry Laboratory II | From course redesign to independent handoff
I redesigned how a course was taught, run, and improved, then made it possible for the next teaching assistant to carry it forward independently.
PAP/ACP3-Targeted Small-Molecule PET Tracers
Think through the work first, then use a sequence of small experiments to remove risks before a costly full experiment.
Total Synthesis of the Jiadifenin Family of Natural Products
A reaction must do more than work once: it needs to be reproducible and scalable enough to keep supplying downstream research.
