Data Analyst for Excel, Google Sheets, SQL and Power BI Dashboards
Sobre este Serviço
Stuck on a query, or is your report too slow? I write, fix and optimize SQL for reporting and analysis: joins, CTEs, window functions and aggregations.
WHAT YOU GET: working, commented query, a short explanation of the logic, performance tips (Premium).
HOW IT WORKS: share the table structure (or sample data), the result you need and your database (MySQL, PostgreSQL, BigQuery, Snowflake, SQL Server), and I deliver a tested query.
