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.

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.

01 · January · Exploring

Falling down the agent rabbit hole

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

02 · February · In the field

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.

03 · March · Systemizing

From "it runs" to "having a method"

Content strategy, decision logs, and pitfall checklists—compressing experience into reusable methodology.

04 · April · Delivery

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.

07 · July · Restarting

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.
