You will get your data extracted and summarized with SQL queries
Project details
Do you need to extract specific data from your database, build a custom report, or summarize large datasets? I'll write clean, optimized SQL queries tailored to your exact needs.
Whether you're working with MySQL, PostgreSQL, SQLite, or SQL Server, I'll deliver well-documented .sql files that you can run, reuse, and modify.
What I can do for you:
-Filter and extract exactly the data you need
-Aggregate and summarize with GROUP BY, JOINs, and subqueries
-Build ranking and comparison reports
-Optimize slow or complex queries
-Export-ready output (CSV, Excel, or direct query)
Not sure if your database qualifies? Message me first — I'll confirm within a few hours.

About Jean
Data Analyst & Excel Automation Specialist | Python, SQL & Reporting
North Bergen, United States - 2:22 pm local time
With 5+ years of Excel experience and a professional background as a Data Analyst in the insurance industry, I've worked with high-volume datasets where accuracy and efficiency were critical. I used Excel VBA to automate workflows and reduce manual processing — real work, real deadlines.
Today I combine that experience with Python (pandas, matplotlib) and SQL to deliver:
- Data cleaning and transformation (ETL)
- Automated Excel/CSV reports with Python
- SQL queries for data extraction and summarization
- Clear visualizations and business summaries
I'm reliable, detail-oriented, and communicate clearly in English. If you have messy data or a manual process that needs automating, let's talk.
