What I have Built
Production-grade backend systems, RAG platforms, and multi-agent runtimes.
PlusAgentPlusAgent
Enterprise-grade Multi-Agent Runtime platform with Orchestrator-Workers architecture for Agent lifecycle management, task orchestration, and multi-Agent collaboration.
- Self-developed state-machine-driven Orchestrator-Workers orchestration engine
- WebFlux/Reactor async event flow with unified Event Protocol and SSE streaming
- MCP JSON-RPC Client with stdio/HTTP dual transport, dynamic tool registration
- Agent Context Pipeline with role isolation, Token Budget control, and Prompt assembly
PlusNexusPlusNexus
Enterprise-grade intelligent search framework with LLM-powered query planning, multi-source data federation, and zero-hardcoding extensibility.
- LLM-powered query plan decomposition into AND/OR/NOT logic trees with PlanCache
- Dual-engine structured extraction (LLM NER + regex) with graceful degradation on LLM failure
- Multi-source data federation with join-key pre-filtering and short-circuit optimization
- Zero-hardcoding extension — new search dimensions added via database rows, no code changes
RagentAIRagentAI
Enterprise-grade Agentic RAG platform with MCP tools and full-stack observability.
- Orchestrated document processing chain (Fetcher → Parser → Enhancer → Chunker → Indexer)
- Intent recognition with tree-structured intent classification
- Multi-channel retrieval with Rerank post-processing
- SSE-based streaming with real-time answer generation
