JOHN C O.

I'm a data analytics and BI professional with 20+ years of experience - 6+ of those leading multi-team analytics organizations in managed care and healthcare. I bring enterprise-level thinking to freelance projects: I know what good data infrastructure looks like because I've built and managed it at scale. What I work on: - Custom dashboards and automated reporting in Excel, Google Sheets, and Google Apps Script - SQL-based data extraction, transformation, and analysis - BI report design and data workflow automation - Healthcare and claims data analysis (HL7, ANSI X12, Medicaid/managed care) - Data cleanup, reconciliation, and financial reporting What sets me apart: I actively use AI tools - including GitHub Copilot and Microsoft 365 Copilot - in my daily work, which means faster turnaround and cleaner code for you. I also bring deep healthcare domain knowledge that most generalist analysts can't match: if your project involves claims data, provider reporting, or compliance-driven deliverables, I've done it at the enterprise level. I work best with clients who have a real business problem to solve - not just a spreadsheet to format. Tell me what you're trying to understand or automate, and I'll tell you how to get there.
