FAQ
What types of data sources and file formats do you work with?
I handle virtually all common formats, including CSV, Excel (XLSX/XLSM), JSON, XML, and plain text files (TXT). For database integration, I work with major platforms like PostgreSQL, MySQL, SQL Server, and SQLite, building optimized queries and scripts for data extraction and loading (ETL).
My data is highly confidential. How do you handle security and privacy?
Your data security is my top priority. I never share or store client data beyond project completion. All files are permanently deleted within 7 days after delivery. I'm happy to sign an NDA if required. Your information stays 100% confidential.
I don't know Python or SQL. Will I be able to run the scripts you deliver?
Absolutely! Every script includes step-by-step instructions anyone can follow. Premium packages include a video walkthrough. If you get stuck, just message me - I provide support to ensure you can use everything I deliver.
What is considered "advanced" SQL for the purposes of this Gig?
Advanced SQL includes complex JOINs, subqueries, window functions, CTEs, stored procedures, and query optimization. Not sure about your project? Message me with details and I'll recommend the right package for you - no obligation!
How quickly can you deliver my project?
Basic packages deliver in 1 day, Standard in 2 days, Premium in 3 days. Need it faster? Select "Extra Fast Delivery" when ordering and I'll prioritize your project for 24-hour turnaround!
What do I receive as the final deliverable for my project?
You receive your cleaned data in your preferred format (Excel, CSV, JSON, etc.). Standard and Premium packages include the Python/SQL script with clear documentation so you can reuse it anytime on new data.
