## About

```text
On my NYC Yellow Taxi Trip Analysis project, I analyzed more than 11 million NYC TLC trip records to answer five business questions. I cleaned the data, created seven features, and used 13 visualizations to identify patterns such as evening demand being about 7.8 times higher than at 04:00.

For my Retail Multi-Source Data Warehouse & ETL project, I designed a warehouse integrating six source systems and built initial and incremental ETL loads. Data reconciliation resulted in zero data loss, and I wrote analytical queries for sales, product performance, and customer profile KPIs.

I’ve also developed web and database projects, including a canteen ordering backend and a campus academic data management application. At POUT, I currently coordinate the Apologetics Class program and mentors while supporting small-group members.
