📌 Featured Project

🔹 Pokeapi ETL Pipeline

ETL pipeline that extracts data from a public API, transforms semi-structured JSON into normalized relational tables, and loads it into MySQL using batch operations.

Highlights:

  • Batch inserts with executemany (performance-oriented)
  • Data normalization (1:N and N:N relationships)
  • Transaction handling (commit/rollback)
  • Modular pipeline structure (extract → transform → load)
