Data, AI and full stack engineer in Seoul. I build data pipelines and the tools around them, work out what the numbers are saying, and ship the apps and AI services that sit on top. When numbers don't match, I go back to the source.
Right now I'm helping LG Uplus move its data warehouse from DB2 to BigQuery.
Projects worth a look
- Change-Data-Capture: MySQL changes streamed through Debezium and Kafka to a live Flask viewer
- python-db-compare: schema, metadata and row-level comparison of two databases, with Excel and Word reports
- LLM-project-RAG: Korean and English RAG, measured with and without retrieval
- Quiz-Management-FastAPI: quiz platform with admin and user roles on FastAPI and PostgreSQL
- Diseases-Prediction-Deep-Learning: heart disease prediction comparing Random Forest, XGBoost, SVM and neural networks
Tools I use most: SQL, BigQuery, Python, FastAPI, React, Go, Tableau, Docker
