À propos de ce service

Need clean data or SQL that actually works? I'm a Data Engineer with 4+ years of experience writing and optimizing SQL and cleaning messy datasets for production systems.

I can help you:

  • Write new SQL queries (joins, aggregations, window functions, CTEs)
  • Fix and debug queries that return wrong or slow results
  • Optimize slow queries so they run faster
  • Clean, deduplicate and standardize messy CSV/Excel/database data
  • Turn raw data into a clear, report-ready table

Works with MySQL, PostgreSQL, SQL Server, and Python (pandas) for cleaning.

You'll get working, documented code and a quick explanation so you can reuse it. I reply fast, deliver on time, and keep your data private.

Not sure which package fits? Message me your dataset or problem and I'll tell you exactly how I'd approach it no obligation.
