Summary
A grouped portfolio view of four representative independent projects, keeping the latest resume structure while preserving project-level detail pages.
Grouped projects
RentBox
2026.05 - 至今A shared rental mini-program system covering user flows, payment guarantees, cabinet state, channel settlement, and operations.
- 按 `server / admin / channel / miniapp / shared / deploy` 组织单仓多端工程，统一用户端、后台、渠道端与部署链路。
- 将订单、支付、免押、开锁、归还、补偿和结算状态收敛到服务端，以幂等、锁、状态历史和审计日志处理外部回调乱序风险。
- 通过 `DeviceGateway`、`DepositFreeGateway` 和回调验签服务隔离柜机厂商、微信支付 v3 与微信支付分，缺配置时返回真实阻塞态。

Paper Retrieval Task Platform
2026.04A user-facing task platform that isolates a customer worker through a database contract while providing task, quota, payment, and admin workflows.
- 使用 FastAPI、SQLAlchemy、Alembic、PostgreSQL、Redis 和 React/Vite 搭建用户端、管理端、任务、支付和额度模块。
- 通过数据库约束与触发器固化 Worker 对 `tasks` 表的状态回写契约，禁止终态回退并要求成功任务具备结果数。
- 实现 LISTEN/NOTIFY、按任务 SSE、多任务 SSE、全局活动任务 SSE 与轮询兜底，让用户侧能持续感知检索进度。

AI Customer Service Runtime
2026 - 至今A governed AI customer-service runtime that supports host mounting, tools, human handoff, knowledge governance, and multi-channel access.
- 设计渠道接入、宿主桥接、核心引擎、业务增强、插件平台、提供商适配六层架构，统一文本、Voice API、RTC WebSocket 与 FastAPI 挂载 4 类接入形态。
- 实现 `route_confidence` 分层、`intent_stack` 回退及 `page_context` / `business_objects` 感知路由，在低置信度与高风险场景优先澄清或转人工。
- 提供 Route、BusinessTool、Handoff、Industry、AuthBridge、Context、Response 7 类插件扩展点，支持宿主鉴权复用与业务能力按需挂载。

WeChat Intelligent Assistant
2025 - 至今A long-running WeChat assistant with transport abstraction, layered memory, RAG fallback, runtime observability, and cost analytics.
- 抽象 `BaseTransport` 接入层并以 `LangGraph` 重构回复主链，将同步回复与后台成长任务解耦，建立适合长期运行的微信助手架构。
- 构建 SQLite 短期记忆、运行期向量记忆与导出语料 RAG 三层记忆体系，支持轻量重排与可选本地 `Cross-Encoder` 自动回退，平衡召回质量与部署成本。
- 补齐 `/api/status`、`/api/readiness`、`/api/metrics`、`/api/config/audit`、成本分析与脱敏诊断支持包，完善运行观测、配置审计与排障能力。

- Evidence level: strict review (core sections only show verifiable metrics)
- Source type: Manual cross-check
- Source link: no public link provided, review against delivery records
- Verified at: 2026-05-18 (30 days ago, fresh evidence)
Rationale: High confidence: organized under strict evidence rules, manually cross-checked, verified 30 days ago.
Background
This grouped project entry mirrors the latest resume's independent-developer section.
Action and Results
Solution
- Present RentBox, the Paper Retrieval Task Platform, AI Customer Service Runtime, and the WeChat Intelligent Assistant as one grouped project area.
- Keep each child project independently traceable through the existing detail routes.
- Reuse the current portfolio structure instead of duplicating a second detail model.
Result
The projects section now shows one parent grouping for independent work while keeping project-level drill-down intact.
