I'm currently solving 100 real-world financial and operational problems in the luxury hospitality industry using SQL.

Each challenge follows a simple structure:

✅ Business Problem

✅ SQL Solution

✅ Business Impact

From basic aggregations to advanced CTEs, the focus is not just on writing queries, but on using data to support business decisions.

I believe practice is the key to master.
