I help businesses solve practical data problems using SQL, Excel, ETL and automation.
I can clean, transform and consolidate Excel or CSV files, develop and optimize SQL queries, automate repetitive data-processing tasks, extract structured tables from PDF files, and prepare reliable datasets for reporting or further analysis.
My services include:
• SQL query development, troubleshooting and optimization
• Oracle PL/SQL procedures and data processing
• Excel and CSV cleaning, transformation and consolidation
• Duplicate removal and data normalization
• PDF table extraction into structured Excel files
• ETL workflows and data validation
• Spreadsheet automation and repetitive-task automation
• Data preparation for reporting and analysis
I have professional experience working with Oracle PL/SQL, Informatica PowerCenter, BigQuery, QlikView/Qlik Sense and large-volume data validation processes.
I focus on small and clearly defined projects that can be completed quickly. Every delivery is checked for accuracy and consistency before it is sent.
If you have a spreadsheet that needs cleaning, an SQL process that needs fixing, files that need to be consolidated, or data that must be converted into a usable format, I can help.
