Nathan Lewis worked on the SAC-LIFE repository for the Sac-State-Mobile-App-The-Nest project, focusing on consolidating and improving the user profile setup flow. He refactored the existing Questionnaire feature into a unified Profile Creation experience, updating navigation, UI classes, and function calls throughout the React Native codebase. Using JavaScript and applying UI/UX development principles, Nathan preserved core onboarding functionality while enhancing consistency and maintainability. His work addressed the need for clearer user onboarding and better data capture, laying groundwork for future analytics and enhancements. The depth of the refactor improved the app’s structure without introducing new bugs or regressions.
