About Me

I turn model capabilities into systems that can be tested, inspected, and shipped. My work connects vision models, LLM agents, retrieval, APIs, and user interfaces—with particular attention to failure handling, traceability, and maintainable engineering.

  • Building multimodal inspection and agent workflows in Python.
  • Contributing production fixes, tests, and typing improvements upstream.
  • Comfortable owning the full loop: issue analysis, implementation, testing, review iteration, and delivery.
  • Sharing AI engineering notes: 200+ followers and 1.5k+ likes on Xiaohongshu.

Open-Source Contributions

15 pull requests merged across 5 external projects. Selected work includes async cancellation, safer agent plugin installation, datasource edge cases, type safety, CI cleanup, MCP tooling, and document processing.

Selected Merged Changes

I value small, reviewable changes backed by focused regression tests and clear maintainer communication.

Featured Systems

Evidence-first multimodal fire-safety inspection. VLM and YOLO outputs flow through specialist review, traceable history, and human feedback.

Vue 3 Flask VLM YOLO

A JD-aware job-search workspace for resume diagnosis and generation, opportunity scoring, application tracking, and interview preparation.

Python Agents Structured Output

A visual inspection system combining YOLOv8 detection with language-model reasoning for behavior and compliance analysis.

Python YOLOv8 LLM Vision

Retrieval experiments in which agents decide when to search, verify evidence, and refine their answers.

RAG Agents Retrieval

How I Build

Evidence-first multimodal AI system pipeline

Current Focus

  • Reliable agent runtimes: cancellation, isolation, tool/plugin boundaries, and observable execution.
  • Multimodal inspection systems that keep conclusions connected to inspectable evidence.
  • Evaluation and regression tests built from real failure cases rather than demo-only success paths.

Current engineering focus: reliability, evidence, and productization


Build systems that do more than predict—build systems that explain what happened.
