At Rakuten, I delivered offline barcode UI and eligibility logic for low-connectivity payment flows. I also implemented fintech package integration and API-connected UI, including token expiry handling and secure Keychain storage.

At Code and Theory, I designed shared SwiftUI components adopted across 3+ teams, reducing UI development time by 35%. I also implemented deep linking and contextual navigation, increasing feature engagement by 30%, and built onboarding and verification modules that improved sign-up conversion by 25%.

I refactored legacy code at Code and Theory to reduce app load times by 20% and crash rates by 15%, and used Instruments to resolve memory leaks and CPU spikes. On my Streaming App project, I built search, trending content, detailed views, and offline caching using MVVM.
