I am excited to share that I have successfully completed all three levels of SQL certification on HackerRank - Basic, Intermediate, and Advanced.

Throughout this journey, I strengthened my understanding of:

Basic SQL: SELECT statements, filtering, sorting, and aggregations
Intermediate SQL: JOINs, subqueries, grouping,
Advanced SQL: Window functions and complex query optimization

These skills have helped me improve the way I analyze data, build logic, and solve real-world business problems. Looking forward to applying this knowledge in future data projects!
