Project details
As an Assistant Manager with 5+ years of experience at a Big 4 firm (KPMG), I specialise in turning messy, unreliable datasets into clean, strategic assets. I don't just "fix typos", I use advanced Python (Pandas) and SQL to audit your data against strict business rules, identifying anomalies that cost you money.
I have successfully led massive data cleansing projects for Bank System Migrations (ensuring 100% readiness) and Telecom Revenue Assurance (detecting leakage).
Why choose this project?
✅Risk Mitigation: I treat your data with the same rigour used for banking clients.
✅Technical Precision: I use scripts to ensure consistent, repeatable cleaning rules—no manual errors.
✅Actionable Deliverables: You receive your clean dataset AND a detailed "Health Report" explaining exactly what was fixed.
Perfect for businesses preparing for a CRM/ERP migration, auditing financial records, or needing a one-time deep clean of customer lists.
