This is my personal learning repository where I track everything I’m practicing and learning — not just for Data Engineering interviews, but also for my own knowledge growth and long-term understanding.
It’s focused on SQL, ETL concepts, data modeling, and theoretical foundations that are essential to becoming a better data engineer.
- SQL, Python practice and problem solving
- ETL concepts and design notes
- Data modeling theory (schemas, normalization)
- System design notes specific to Data Engineering
- Quizzes, summaries, and personal notes
- Learning logs and source references
- https://www.sql-practice.com/
- https://sqlzoo.net/
- learnsql (mobile app)
- YouTube tutorials
- Articles, blogs, and documentation
This repository is primarily for my own learning and progress tracking.
If it helps someone else — that’s a bonus.
