TL;DR

  • 定位：上海全栈工程师（Fintech），面向生产环境做 Agent/LLM 工程化。
  • 方向：把 AI 能力“嵌入”现有企业基础设施（权限、审计、稳定性、可观测）。
  • 开源：agent4j —— Java-native Agent SDK（插件化工具 + 流程编排）。

What I’m good at

Production Engineering

  • High-concurrency, reliability-first backend (Fintech)
  • Observability: metrics/logs/tracing, incident-driven iteration
  • Security & compliance constraints in real systems

Agent/LLM Engineering

  • Tool integration with guardrails (policy, audit, retries)
  • Workflow orchestration & deterministic replay
  • Evaluation mindset: regression sets, cost-aware routing

🇺🇸 English

A Shanghai-based Full-stack Engineer with a deep background in Fintech. I believe AI capabilities should be seamlessly integrated into existing industrial-grade infrastructures, not decoupled from them.

Core Tech: Java (10y+) + Vue 3 (2y+)
Mission: Filling the gap in the Java ecosystem for AI Agent frameworks, enabling enterprises to embrace the Agentic era without friction.

agent4j is an AI Agent framework for Java developers.

  • Problem: Many enterprise systems run on Java, yet agent frameworks are dominated by Python/JS.
  • Solution: agent4j provides a Java-native Agent SDK with tool/plugin integration and workflow orchestration.
  • Goal: Production-first stability and performance — a pragmatic foundation for real teams shipping agentic apps.

What I’m looking for

  • Roles: Backend/Full-stack · Agent platform/infra · Fintech engineering
  • Collaboration: Open-source co-building, enterprise pilot integrations, technical writing/speaking
