The Problem
I wanted focused, hands-on practice with the SQL patterns that come up constantly in real data work — subqueries, conditional aggregation, and correlated queries — beyond what a single course project would cover.
/02
What I Did
I built and organized a collection of SQL scripts covering core relational database operations: subqueries, HAVING clauses, EXISTS operators, and correlated subqueries, applied across data manipulation and analysis tasks.
/03
What I Found
Working through these patterns repeatedly built real fluency with query structures I now reach for naturally when exploring a new dataset, rather than looking them up each time.
