Build Complex Into Systems

12 years of B2B product & systems experience, with the last 4 years focused on AI + product delivery. Shipped a vertical AI product end-to-end from 0 to 1, well-versed in Agent architecture and MCP protocol. I turn business abstraction, system design, AI workflows, and measurable delivery into a closed loop. Let the work speak for itself.

BXZ Platform

Product Owner · Full-stack Architect · Solo Delivery

An online efficiency platform for standardization professionals. The system uses a proprietary MinHash text fingerprinting algorithm and structural analysis engine to check compliance and cross-reference consistency, generating 11-step end-to-end structured review reports. It features "Call BXZ" AI assistant — built on RAG retrieval-augmented architecture (FTS full-text index + BM25 ranking) with an 8-intent recognition engine (regex fast-path + LLM fallback), AI Guardrail (regex pre-check + System Prompt injection protection), Prompt engineering standards, and Dual Provider failover + SSE streaming. Commercialized via WeChat Native Pay + 3-tier membership system.
