• Designed frontend architecture using React, TypeScript, and RadixUI for staff portal and client-facing applications
• Built TypeScript SDK generator from Swagger documentation, ensuring type-safe frontend/backend contracts during rapid MVP development
• Built design system foundations in Figma and code, establishing component library and design tokens
• Conducted user research with clinical and administrative teams to understand workflow pain points and accessibility requirements for neurodivergent client base
• Created interactive prototypes in Figma to validate designs before development
• Supported backend engineers with API design (Ruby on Rails) and database schema decisions for event scheduling and treatment plans

Hired to create Unit4's design system (Ripple) from scratch, establishing strategy, team, and technical foundations.

• Architected monorepo codebase using nx with CI/CD pipelines in Azure, publishing to private npm registry and deploying Storybook documentation
