Open-source agent mall backend that integrates Coze APIs to sync agents/workflows/apps into local storage with incremental insert/update/delete. Provides pricing in the admin console. Integrated Shouqianba payments with pre-created orders, frontend polling, callbacks, and scheduled close-order fallback; added idempotency and rate limiting, plus recharge, points conversion, and consumption deduction with points/balance ledgers for traceability. CI/CD automated with GitHub, Jenkins, and Docker.

Meter after-sales quality system built with NestJS + Prisma + Vue3. Covers events, work orders, repairs, logistics, notifications, dictionaries, statistics, and after-sale agreements with JWT auth, Redis caching, and MinIO storage, with Grafana/Prometheus monitoring. Based on AI Vibe Coding, I delivered rapid MVP iterations; Prisma's code-first workflow enables code-led schema sync and fast releases. Also delivered UML diagrams, user manuals, and standardized technical docs generated via custom skills.

Internal HR system at Jiangyin Zhonghe built with NestJS + Prisma + React + Ant Design. Covers org/employee, approval templates and workflows, attendance, payroll, recruiting, performance, announcements, and push notifications, with file upload and object storage and Grafana/Prometheus monitoring. Also built a React Native mobile app with multi-platform adaptation for Android/iOS. Based on AI Vibe Coding, I delivered rapid MVP iterations; Prisma's code-first workflow enables code-led schema sync and fast releases. Also delivered UML diagrams, user manuals, and standardized technical docs generated via custom skills.

Mini program backend with Spring Security and RBAC authorization. Unified device management APIs with a base device model and business codes for multi-type devices, wx-java login integration, and HttpClient-based vendor API calls.

Greenhouse management backend (Java 8 + Spring Boot) with environmental monitoring (light/temperature/humidity), plot management, crop and planting plan management, and plan templates. Integrates crop growth models for yield prediction using light/temperature factors, with Spring Security + RBAC, scheduled jobs, and async updates for plan workflows.

WeChat mini-program backend with login, QR code generation, subscription messages, and content security checks, covering booking, room/bed management, and visitor/seminar/interview/social service records; uses Redis/Redisson for consistency and integrates MinIO storage.

IoT middle platform backend on Spring Boot/Spring Cloud Alibaba, integrating unmanned farm machinery positioning, temperature sensors, soil detectors, and other agricultural devices. Handles multi-protocol access (HTTP/MQTT/AMQP) via Netty async non-blocking I/O; Kafka ensures high-throughput message flow with idempotency and reliable delivery. Supports custom mapping rules for ETL transformation before persisting to MongoDB (object models, device data) and MySQL (product info). Upstream/downstream integration uses thread pools with Sentinel rate limiting/circuit breaking, retry mechanisms, and trace logging for stability and observability.

Rule-driven auto release for freight orders. Built rule management and execution pipeline with Aviator expressions; supports user-bound rules with AND/OR logic. Manual trigger filters eligible orders; scheduled auto mode runs nightly, joins multiple tables to select last-month orders and invokes the rule engine in parallel.

Independent value-added service for CARGOWARE, integrating port APIs (Shanghai, Ningbo, Tianjin) for ocean freight. Supports full and incremental sync, manual order sync, and idempotent processing. Uses SpringBoot @Scheduled + Redisson locks, thread pools, Redisson delayed queues for rate limiting (60/min, >=1s), HttpClient fetch/parse, Caffeine local cache plus Redis caching by vessel/voyage, and RabbitMQ notifications to billing and downstream systems.

Auto reconciliation with configurable import templates and comparison rules. Parses supplier Excel via Apache POI and caches mapped data in Redis per template/user; uploads raw files to storage. Reconciles by rule-defined dimensions using Java Stream grouping, compares detail/summary, flags differences, and paginates results.
