About this Gig

I will write clean, efficient SQL queries and turn your raw database data into clear reports you can use. I work with financial and trading data every day, so accuracy and clear logic matter to me.


What I can do:

  • Custom SELECT queries with joins, aggregations, window functions and CTEs
  • - Debug and speed up slow queries
  • - Reports and summary tables (daily, weekly, monthly)
  • - Views and scheduled extracts
  • - Excel dashboards connected to your results

Works with MySQL, PostgreSQL, MS SQL Server and SQLite.


How it works: send me the table structure (or a small sample) and tell me what question you need answered. I write and test the query, add comments so you can reuse it, and deliver it with a short explanation.


Please do not share passwords or production credentials. A schema and sample data are enough.
