I build .NET APIs and data platforms for regulated financial software.

United States
Message

I'm building the SQL Server schema, Python data pipelines, and .NET APIs behind PGIM Custom Harvest's tax-managed portfolio proposal platform. My work includes reliable PDF-to-SQL price extraction, auditable sector-weight data, and API features for reference data and proposal workflows.

Previously at Donnelley Financial Solutions, I shipped full-stack features for ArcReporting, a SaaS platform investment firms use for SEC-compliant shareholder reports. I built React and TypeScript review experiences, REST APIs, workflow state tracking, and audit-ready change history for regulated filing processes.

At Case Works, I built .NET Core services and REST APIs for legal and insurance case management, integrated Azure Service Bus into microservices, and improved CI/CD reliability. I also built StockTree, a domain-driven investment portfolio platform that reconstructs account history from brokerage activity.
