• Led a full navigation refactor of the Chewy iOS app, resolving broken tab-context and backstack behavior across core surfaces. Designed and implemented a tab-agnostic navigation architecture that unblocked major feature work, improved UX consistency, and reduced navigation-related regressions.

• Built and launched platform-critical features, including: passkey login for secure, passwordless authentication and a Vet Care scheduler enabling in-app appointment booking via hybrid web integration. Delivered performant, scalable UI using SwiftUI, UIKit, and WebKit.

• Improved developer experience by standardizing engineering workflows and raising code quality standards. Authored internal documentation for common tasks, promoted clearer PR practices, and contributed to shaping team-wide development norms for faster onboarding and long-term maintainability.

Implemented out of thread user experience in Objective-C and Swift for Boards on iOS, an Instagram product available to ~2 million users, to enable synchronous content sharing and co-creation in direct messaging threads.

• Conducted molecular biology research on cardiac glycoside biosynthesis in Erysimum (wallflower). Cloned pSRK expression vectors in E. coli, expressed OSC genes, and prepared protein samples for GC-MS analysis.

• Developed and refined a computational model of Sendai virus fusion kinetics using MATLAB’s ODE solver, translating biochemical mechanisms into first-order rate equations to simulate membrane fusion dynamics.

• Collaborated with faculty mentors across biology and chemistry departments, integrating lab-based experimentation with computational modeling to explore plant and viral biochemical pathways.

• Implemented end-to-end admin moderation flows in Messenger community chats, strengthening tools for managing safety and conversation quality in large-scale group environments of 5000+ members.

• Built responsive Android UI components using Kotlin and Litho, integrated with backend services, and handled state management to ensure a smooth and consistent user experience. Wrote unit tests achieving 85%+ code coverage to ensure feature reliability and deployment to Messenger’s over 1 billion users.
