Clinical medicine student · using AI-assisted tools in my spare time
to build things that actually run in the real world
A post-2005 clinical medicine student in training 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, turning the messy customer service, data, and reports inside real businesses into systems that run themselves every day. More than writing code line by line, I want to understand how to make what AI produces actually hold up in the real world.

Selected projectsSELECTED PROJECTS
CASE 01
Business data automation: dashboard + report bot
Automated data pulls, metric-definition governance, a real-time dashboard, and scheduled WeCom group distribution with a hard approval gate. Management can see operating data directly on their phones.
CASE 02
WeCom AI customer service for a medical aesthetics business
Layered AI + human collaboration, coordinate calibration across dual vision models, process supervision, and health checks. Already in production at real store locations.
OPEN SOURCE
Three upstream PRs for the medical module of a 40,000+ star open-source project
Added medical publishing policies and a fail-closed disclosure workflow, a Chinese literature parsing client, and an EQUATOR reporting guidelines module to Academic Research Skills. The three PRs passed multiple rounds of adversarial review and were all merged from 2026-08-01 to 08-02; the umbrella issue was closed as completed by the maintainer.
On stage · RecognitionON STAGE
Engaged by JD.com (Zhengzhou) Merchant Service Center as a training instructor for “AI Implementation in Practice” (2026.4–11), and I've also spoken at local AI sharing events about my real hands-on practice. Related media coverage →
About me · 2026 journeyABOUT & JOURNEY
I first got into AI at the start of 2026—from zero Vibe Coding to entering a real enterprise environment in two months. I am not a trained programmer, and right now I still cannot write complex systems without AI. My edge is understanding real business: breaking problems down into data, process, state, and verification criteria, then using AI-assisted coding tools for prototyping, debugging, deployment, and iteration. When it comes to professional engineering issues like underlying architecture, security, and high concurrency, I need professional engineers to review and collaborate.
Personal Vibe Coding beginnings
From zero, I used AI-assisted coding—from automation scripts to small tools—to train myself into someone who can actually ship things.
Falling down the agent rabbit hole
Claude Code, OpenClaw, memory systems, multi-agent collaboration—first, turn myself into a heavy user.
Entering a real enterprise environment
Medical aesthetics customer service, Douyin lead sync, and the Xiaohongshu matrix all kicked off at once—the first time I faced real delivery pressure head-on.
From "it runs" to "having a method"
Content strategy, decision logs, and pitfall checklists—compressing experience into reusable methodology.
Production awareness awakens
Customer service system production hardening, failure alerting, and incident post-mortems—shifting from "player" to "deliverer".
Back to school for finals
Medicine is my anchor. I went back to school to prepare for exams and paused AI development—keeping my studies on track is itself a form of delivery.
Full-time, back on the road
Started full-time over summer break: my personal site launched from zero and went through proper engineering hardening, AI customer service kept iterating in production, and the first batch of engineering retrospectives were written up.
