Project details
Get 100% Accurate, Analytics-Ready Business Data Automated by Python
With over 9 years of professional experience in corporate data processing (including NielsenIQ), I specialize in cleaning, validating, and structuring messy CRM and sales datasets.
What sets this project apart:
Advanced Automation: I don't just clean your data manually. I build custom Python scripts (using pandas/numpy) to handle anomalies and automate your recurring data tasks efficiently.
Direct Database Connection: Beyond flat files (Excel/CSV), I can securely connect directly to your SQL databases (MySQL, PostgreSQL) or Google BigQuery to clean data right at the source.
Enterprise-Grade Accuracy: Having handled large-scale data for global brands like Piaggio and Castrol, I ensure your database is completely optimized for CRM platforms or Power BI dashboards.
