Clinical medicine undergrad · I use AI-assisted tools in my spare time
to build things that actually run in the real world

A post-2005 clinical medicine undergrad transformed by AI. During the day I move between the hospital and textbooks; the rest of the time I work alone with AI-assisted coding tools to turn the messy customer service, data, and reports of real businesses into systems that run themselves every day. Rather than writing every line by hand, I care more about figuring out how to make AI-written code actually hold up in the real world.

Appointed by JD.com (Zhengzhou) Merchant Service Center as a training instructor for the “AI Implementation in Practice” track (2026.4–11), and I also take the stage at local AI sharing events to talk about my real, hands-on practices. Related media coverage →

About me · 2026 journeyABOUT & JOURNEY

I first encountered AI in early 2026—it took two months to go from zero-background Vibe Coding to entering a real enterprise environment. I'm not a classically trained programmer, and right now I can't independently write complex systems without AI. My edge is understanding real business: breaking problems into data, flows, states, and verification criteria, then using AI-assisted coding tools to carry prototypes through development, debugging, deployment, and iteration. When real engineering issues arise—low-level architecture, security, high concurrency—professional engineer review and collaboration are necessary.

Early ’26 · Awakening

Personal Vibe Coding beginnings

Zero-background, AI-assisted coding: from automation scripts to small tools, training myself into someone who can make things independently.

01 · January · Exploring

Down the agent rabbit hole

Claude Code, OpenClaw, memory systems, multi-agent collaboration—first make myself a heavy user.

02 · February · Hands-on

Entering a real enterprise environment

Medical aesthetics customer service, Douyin lead sync, and the Xiaohongshu matrix all kicked off at once—my first direct exposure to real delivery pressure.

03 · March · Systemizing

From “it runs” to “there’s a method”

Content strategy, decision logs, a list of pitfalls—compressing experience into reusable methodology.

04 · April · Delivery

Production awareness kicks in

Production hardening for the customer service system, failure alerts, incident post-mortems—from “player” to “someone who delivers.”

Back to campus for finals

Medicine is my safety net. I went back to school to prepare for exams and paused AI development—keeping my studies on track is itself a form of delivery.

07 · July · Restarting

Full-time, back on the road

Full-time over the summer: my personal site launched and was properly engineered, the AI customer service kept iterating in production, and the first batch of engineering retrospectives was written up.
