## About

```text
At XOXODAY, I worked on mobile products including Channel Partner, GiiftCompass, and Compass. For Channel Partner, I led the architecture of an enterprise loyalty app and co-designed Apollo GraphQL schemas that cut redundant payloads by 35%.

For GiiftCompass, I led the migration from native iOS to React Native with Expo CNG and native TurboModules in Swift and Kotlin. I also automated releases with Fastlane and EAS, cutting deployment time from two days to under 30 minutes.

On Compass, I built modular iOS flows and networking with UIKit, Swift Concurrency, and Core Data. Across these products, I worked on offline-first transactions, app stability, and performance improvements for iOS and Android.
