The problem

Data had to move between different databases and applications, with transformations that matched the receiving system.

My contribution

  • Developed on-premise ETL flows.
  • Used SQL and Python for data transformations.
  • Worked on the database and API interfaces around the pipelines.

Evidence & scope

The work included checking transformations and the interfaces used to exchange data.

What came out of it

ETL flows connecting the source databases and applications.

Practical data-engineering work across ETL, databases, and API management.
