PRODUCT BUILDER · FULL STACK · AIPM

I explore AI's emerging frontiersand turn ideas into commercial reality.

I'm working toward becoming a full-stack product manager. Most recently, I independently took Vidmuse Free Canvas through a self-directed 0→1 closed loop, completing a vital piece of Vidmuse's AIGC ecosystem—an exhilarating and unforgettable experience. You're also welcome to try Personal Treehole, my own anonymous sharing space.

2022 · ORIGIN

A road I chose not to follow.

I graduated in civil engineering in 2022. Rather than inherit a path that did not fit the life I wanted, I chose to change direction.

2022—2023 · CODE

Starting again, from code.

With no computer-science background, I taught myself Java and made my first career change. It proved that a starting point does not have to become a destination.

WORK × STUDY

Two lives, running in parallel.

After becoming a developer, I prepared for graduate school alongside a full-time job—shipping work by day and becoming a student again at night.

UCAS · ARTIFICIAL INTELLIGENCE

The answer changed the question.

I was admitted to the University of Chinese Academy of Sciences to study artificial intelligence. The offer made me ask a better question: what did I truly want to build?

A NEW DIRECTION

Choosing to begin again.

I stepped away from pure development and started again through internships, moving closer to the point where models, users, business, and product decisions meet.

YEAR ONE · RESPONSIBILITY

Carrying more than one role.

In my first graduate year, I worked while studying and served as class monitor. Balancing work, study, and responsibility earned me the Outstanding Student Leader honor.

YEAR TWO · NOW

I've come a long way.

In my second year, I was named a Merit Student. From civil engineering to Java, from developer to AI graduate student and product builder—my road was never straight, but every turn made it clearer.

DAILY PRACTICE

06:00

Before the day begins.

I now train at six every morning before work. Through years of change, exercise has helped me release emotion, restore order, and keep a promise to myself each day.

Some choices moved me forward. Training kept me steady.
