Hi, I'm however-yir

AI Engineer & Java Backend Developer working on knowledge retrieval, business agents, and backend reliability.

专注 AI 应用工程与 Java 后端：让知识问答有据可查，让业务 Agent 的动作可控，让系统改动有验证依据。

Featured Projects

Project Engineering focus Explore
KnowledgeOps Agent Spring AI platform prototype: tenant-scoped RAG, asynchronous document ingestion, answer citations and evaluation. Demo · Design · Evidence
Tianji AI Agent Course-advisor Agent: intent routing, governed order previews, execution budgets and SSE contracts on an existing business backend. Demo · Design · Evidence
NebulaKB Django knowledge operations: document ingestion, retrieval feedback and low-quality answer review. Demo · Design · Evidence
ForgePilot Studio OpenHands-based workbench: task console, audit tooling and experimental governance modules. Demo · Design · Evidence
Microservices Lab Online Boutique extension: AI shopping assistant, local model fallback and Kubernetes integration. Demo · Design · Evidence
ragproof Framework-agnostic RAG evaluation CLI: recall@k, MRR, faithfulness, citation metrics, regression gates and CI integration. Demo · Design · Evidence

Start with KnowledgeOps for the Java/RAG platform, then Tianji for business Agent execution.

For inherited code and project-specific changes, see the project scope and provenance guide. ForgePilot's core governance modules are experimental and are not wired into the default OpenHands execution path; its design links describe that boundary.
