Hi there I'm Tim or Yu-An,Chen ๐Ÿ‘‹

๐ŸŒฑ ย  About Me

  • ๐Ÿ  ย  From Taiwan TW: and currently based in Taipei, Taiwan
  • ๐Ÿ’ฌ ย  Talk to me about Full Stack, Docker and Data Engineer

I built a GitHub Data Analytics Pipeline leveraging GCP, Airflow, and BigQuery to automate the processing of GitHub Watch events and deliver real-time insights into open-source trends and developer engagement via a Streamlit dashboard.

I built a clothing recommendation platform that integrates web scraping, ETL, Redis caching, a FastAPI backend, and a React frontend to provide outfit suggestions based on location styles, color palettes, and gender filters.

I built a full MLOps pipeline for stock price prediction, featuring automated ETL, model training, experiment tracking, real-time inference, monitoring, and CI/CDโ€”powered by FastAPI, Prefect, MLflow, and Grafana on a Dockerized infrastructure.

I built an AI-powered ArXiv Knowledge Retrieval Platform, implementing daily ingestion of papers, PDF/metadata storage (PostgreSQL/MinIO), vector-based retrieval (Qdrant), and LLM-powered Q&A with bilingual support, alongside a React dashboard for query history, analytics, and subscription management, orchestrated via FastAPI and Prefect, fully containerized with Docker and monitored with Prometheus/Grafana.
