however-yir/README.md

Hi, I'm however-yir

AI Engineer & Java Backend Developer focused on building deployable, verifiable, and operable AI engineering systems.

Portfolio: however-yir.github.io — 6 AI matrix projects · RAG · Agent · Knowledge Ops · Cloud Native

Currently focused on:

  • Spring AI, RAG, tool calling, MCP, and multi-agent systems
  • Java / Spring Boot enterprise backend engineering
  • Enterprise knowledge bases, intelligent Q&A, recommendation systems, and AI workflow platforms
  • AI application engineering across auth, security, evaluation, observability, CI/CD, and deployment

Featured Projects

AI Engineering Matrix

The six AI repositories are designed as one portfolio system rather than isolated demos:

KnowledgeOps Agent  -> platform baseline: RAG, workflow state, memory, evidence, observability
Tianji AI Agent     -> business agent case: routing, tool calling, SSE, structured UI payloads
NebulaKB            -> knowledge operations: ingestion lifecycle, governance, quality feedback
ForgePilot Studio   -> engineering execution: task protocol, runtime, audit replay, MCP tools
Microservices Lab   -> cloud-native layer: multi-language services, K8s, gRPC, AI integration
Campus Recruitment  -> recommendation system: collaborative filtering, data pipeline, frontend
Project Case Study Stack
knowledgeops-agent Portfolio → Spring AI, RAG, JWT/RBAC, Observability
tianji-ai-agent Portfolio → Java, Spring AI, Tool Calling, MCP, SSE
nebula-kb Portfolio → Django, PostgreSQL, Redis, RAG + DeepDoc, Open WebUI
forgepilot-studio Portfolio → Python, FastAPI, React, MCP
however-microservices-lab Portfolio → Go, Python, Java, Node.js, C#, K8s, gRPC
campus-recruitment-recommendation-system Portfolio → Spring Boot, Vue2, MySQL, Collaborative Filtering

Technical Review Path

  • 10 minutes: read however-yir.github.io, open knowledgeops-agent and tianji-ai-agent, then scan each README hero, architecture image, quick-start command, and release note.
  • 30 minutes: open each repository's docs/evidence/ pack, CI workflows, demo script, screenshots, and local run notes to verify that the projects are runnable and observable.
  • Source deep dive: start with KnowledgeOps workflow/RAG/memory modules, then Tianji routing and SSE agents, NebulaKB lifecycle services, ForgePilot control plane, and Microservices Lab deployment paths.

Full cross-repository demo mainline: docs/ai-matrix-demo-mainline.md.
