Built the shared primitives library and services behind several Optum operations apps

The challenge

Several internal applications for healthcare and pharmacy operations were each solving the same problems: the same controls, the same layouts, the same backend capabilities, built slightly differently in every codebase. Business ideas arrived at a high level and had to become consistent, working software across all of them while the tools stayed in daily use.

Approach

• Helped build a shared primitives library that several internal applications adopted, so common controls were designed and fixed once instead of in every codebase
• Helped build the microservices those applications consumed as a shared layer, supplementing each product's own backend rather than replacing it
• Served as the link between business stakeholders and engineering, turning high-level ideas into working screens and keeping cross-functional projects clear and moving
• Introduced AI-assisted workflows to the team, bringing GitHub Copilot into both planning and development before it was standard practice
• Mentored junior engineers and raised the floor in code review, documenting patterns so they stuck
