Whether from spreadsheets, APIs, or databases, your data becomes consistent, analysis-ready, and reusable through seamless data transformation and data integration.
My approach removes duplicates, corrects inconsistencies, handles missing values, and performs precise data reconciliation to align data across sources. You’ll receive a clean, documented dataset reflecting proper data integration and verified through strict data reconciliation.
This project combines precision, automation, and clarity, turning messy information into trusted knowledge through expert data transformation, data reconciliation, and data integration.

Shopify CSV Data Merge & Cleanup (Google Sheets → Shopify Format)
Polite communication throughout the project, however the final CSV was not production-ready and required substantial rebuilding on my side after Shopify import validation.
The project also significantly exceeded the original estimate despite an upfront request to notify before going over budget.
I would recommend stronger QA and more accurate scope estimation for future production data projects.
