AI Application & Full-Stack Engineer · Open-Source Contributor
I build LLM gateways, model-evaluation tools, digital-human workflows, and reliable AI applications.
专注 LLM 网关、模型评测、数字人和 AI 应用，也参与 Java 量化交易平台的开源贡献。
- AI applications: self-hosted digital humans, RAG, LLM agents, and human-in-the-loop workflows.
- LLM infrastructure: self-hosted gateways, streaming transports, model evaluation, and usage diagnostics.
- Developer experience: diagnostic tools, automation, reproducible builds, and evidence-first debugging.
- Open source: focused, test-backed contributions to active AI and developer-tooling communities.

| Date | Update |
|---|---|
| 2026-10-21 | Released CPS Codex Candy Eval v0.1.2: reasoning tasks, model behavioral fingerprints, SVG drawing previews, and account-based test history; adapted to CPS v3.29.7. |
| 2026-10-20 | Codex Proxy RS #484 merged: base pooled WebSocket circuit breaking on actual connection results so slow successful connections do not count as failures. |
| 2026-10-19 | Published Model Health Plugin v0.3.2 from my fork: CPS v3.29.3 protocol compatibility and batch testing. |
| 2026-10-13 | Codex Proxy RS #412 merged: color-coded first-token and total latency across usage views. |
Plugin releases above are locally/offline validated; live CPS installation and real-model billing checks remain pending.
Selected projects with merged PRs or direct upstream commits. Star badges reflect each upstream repository.
