About
Yu-An Chen (Tim)
Backend & AI / Data Engineer · Taipei, Taiwan
Building AI and data systems that actually run in production — and turning the decisions into documentation.
Backend engineer with hands-on MLOps experience. Comfortable across cloud infrastructure (GCP, Docker, Ansible) and data pipelines (Airflow, Prefect, PySpark), with a focus on shipping AI into production — RAG systems, model monitoring, and automated training workflows.
Principles
- Technical decisions as documentation — the process is often worth more than the conclusion.
- What's needed isn't more output, but lower-cost understanding.
- The real value of engineering is reproducibility and maintainability.
