Warburg Pincus — Quill Application
Warburg Pincus is a private equity firm with over 55 years of experience in growth investing across sectors including Consumer, Energy Transition, Financial Services, Healthcare, Industrial & Business Services, Real Estate, and Technology. Quill was an internal deal management application built to give 300+ deal professionals a faster, more intuitive tool for tracking and analyzing financial data across their portfolio.
Project Scope
This was a six-engineer project working inside Warburg Pincus’s existing Microsoft Azure development environment. The application was built in React with AG Grid for tabular data display and charting libraries for visualizations. Dashboards needed to be flexible across all deal types in different industries, and each deal could be updated by over 100 authenticated users — making state management and asynchronous update handling a core architectural concern.

My Role
I was responsible for building out modals involving state management, implementing real-time state change notifications within the UI, creating data visualizations from API-sourced financial data using graphing libraries, fixing bugs across the application, and integrating with iLevel and other third-party portfolio management systems.
My contributions produced ten dashboard visualizations that were put into active use by deal professionals. The complex tabbed interfaces supported investment valuations, multi-page financial reporting, and flexible metric display across industries.
