You will get optimized SQL queries and deliver a clear data analysis report
Project details
Do you have a database full of data but no clear answers to your business questions?
I will write clean, well-commented SQL queries to extract exactly the insights you need — and deliver them in a clear report with findings and recommendations.
What I can analyse:
→ Sales performance and revenue trends
→ Customer segmentation and RFM analysis
→ Product profitability and top-N rankings
→ Month-over-month and year-over-year growth
→ Data cleaning and deduplication
→ KPI calculations (conversion rate, churn, retention)
SQL techniques I use:
→ CTEs, Window Functions (RANK, LAG, DENSE_RANK)
→ Multi-table JOINs, subqueries, CASE WHEN logic
→ Aggregations and conditional aggregation
→ Date functions and rolling totals
Send me your schema or CSV files and your business questions. I will deliver clean, readable SQL + a summary of key findings.
Databases supported: MySQL
