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. National map drill-down, customer CRM, Excel batch import. Now in pilot use.
7-day 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. 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 CI/CD. Live at system.kaixingwuliu.com, currently in pilot use.
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), and reflections on PM + AI collaboration.
