🚀 Hi, I'm Xi Chen

Incoming AI Graduate @ University of Adelaide | Ex-Baidu Intern

I am a software engineer passionate about bridging the gap between Cloud Infrastructure and Artificial Intelligence. With a background in developing high-availability cloud phone systems at Baidu, I am now focusing on building scalable AI applications.


⭐ Featured Project

cloud-ops-ai-agent — Async Industrial Execution Engine

An experimental framework merging Baidu Cloud-Phone operational patterns with modern async AI agent design. Built as a flagship project to demonstrate production-grade cloud orchestration:

Feature Implementation
Bounded Concurrency asyncio.Semaphore for multi-device batch management
Three-Phase Safety Gateway Risk classification → Identity verification → MFA (mirrors Baidu account security)
Cooperative Task Abort CancellationToken + raise_if_cancelled() at high-frequency checkpoints
Config-Driven Zero hardcoding — all params from config.json
Observability TraceID full-chain, Prometheus metrics, AWS S3 log persistence
AWS Academy S3 audit logs with Learner Lab session-token support

Python · asyncio · boto3 · Prometheus · CI/CD (pytest, flake8)


🛠 Technical Stack

  • Languages: Python (asyncio, Deep Learning), TypeScript, Golang, SQL
  • AI/ML: PyTorch, LangChain (RAG), OpenCV, Hugging Face
  • Cloud/DevOps: AWS (EC2, S3, STS), Docker, Kubernetes, CI/CD (GitHub Actions)
  • Front-end: React, Next.js, H5 Optimization (Performance Focused)

🏢 Professional Experience (Highlight)

Baidu (Guangzhou Duling Technology) | Front-end & System Intern

Role: Cloud Phone Product Optimization

  • Scalability: Refactored static documentation into a cross-platform (PC/Android/H5) configurable back-end system, reducing deployment cycles.
  • Security: Implemented advanced verification mechanisms for high-risk cloud phone operations, significantly enhancing user data safety.
  • UX/DX: Designed task termination workflows for automation products, improving system controllability.

→ These patterns are now codified in cloud-ops-ai-agent as a reusable async execution engine.
