Solo, 7-day end-to-end build for a chemical-trading company — research → React/Node full-stack → Aliyun ECS deployment. A Vibe-Coding practice in which I owned business understanding, spec, and QC; AI accelerated the code. The visualization-based customer management system (national map drill-down, customer CRM, Excel batch import) is live and in pilot use. A second part — internal data classification & matching — is in progress: I've turned its SOP into a workflow and a Skill, and aim to ship it as an Agent.
Solo end-to-end build for an anonymous chemical-trading client — covering 3 product lines (soda ash, urea, sodium bicarbonate) across 5 sales zones and 31 provinces. The project has two parts. Part 1, the visualization-based customer management system, was built in ~7 days as a Vibe-Coding practice (I owned the business interviews, the spec, the QC; AI accelerated the React + Node + Prisma + PostgreSQL build; I drove the Aliyun ECS deployment with Nginx + PM2 + GitHub Actions). It is live at system.kaixingwuliu.com and in pilot use. Part 2, internal data classification & matching, is in progress: I've turned the SOP into a workflow and a Skill, and the goal is to ship it as an Agent. Because that part carries client-specific details, it has no public UI here.
Chinese version below — covers the business interviews, what Vibe Coding looks like when PM-driven, the system architecture, the 7-day timeline, the data-model decision that mattered most (1:N customer-region), the in-progress data-matching workflow/Skill/Agent, and reflections on PM + AI collaboration.
