Summary
Led four representative projects across rental workflow delivery, task-platform integration, customer-service runtime design, and a long-running desktop assistant, covering design, implementation, integration, testing, and runtime governance.
Grouped projects
RentBox Shared Window-cleaning Device Mini Program
2026.05 - 至今Independently delivered a multi-client rental system covering mini program, admin console, channel portal, and Spring Boot backend across payment, deposit-free rental, device commands, returns, settlement, and audit paths.
- Organized server, admin, channel, miniapp, shared, and deploy modules in one verifiable delivery loop.
- Built server-side state machines for orders, payments, devices, returns, compensation, and audit logs.
- Integrated WeChat Pay v3, WeChat Pay Score, and device-vendor Web APIs behind gateway boundaries.

Paper Retrieval Task Platform
2026.04Delivered a user-facing task platform around phone verification, task creation, shared worker-table integration, SSE status updates, quota ledger, Alipay upgrade, and admin operations.
- Built user, admin, task, payment, quota, and health-check modules with FastAPI and React.
- Integrated with the customer worker through a shared database contract instead of direct coupling.
- Used PostgreSQL triggers, LISTEN/NOTIFY, and SSE to keep task status visible.

Background
This is the independent-developer stage described in the latest resume, spanning multiple AI application and full-stack projects in parallel.
Action and Results
Solution
- Consolidated RentBox, the Paper Retrieval Task Platform, AI Customer Service Runtime, and the WeChat Intelligent Assistant under one parent work item.
- Kept design, implementation, integration, testing, and runtime governance visible from the parent view.
- Preserved each child project's independent slug and detail route for drill-down.
Result
The portfolio now reflects the latest resume structure without losing access to project-level evidence.
Key Signals
Grouped RentBox, the Paper Retrieval Task Platform, AI Customer Service Runtime, and the WeChat Intelligent Assistant under one independent-developer work entry. Kept each child project traceable through its own slug, evidence notes, and detail page. Aligned the public portfolio structure with the latest Chinese resume and English PDF. Tech Stack
