What I'm looking for

I seek roles building consumer-facing iOS apps using SwiftUI and modern concurrency, collaborating with product/design, and owning reliable, testable releases.

I am an iOS engineer with six years of experience building production apps, modernizing legacy projects, and contributing to Apple’s Develop in Swift curriculum. I embrace SwiftUI and structured concurrency to create maintainable, performant applications that delight users.

At Nutrisystem/Jenny Craig I transitioned UIKit codebases to scalable Swift/SwiftUI apps, implemented XCTest suites, StoreKit 2, REST API integrations, and payment flows. I helped increase engagement and reliability through testing, profiling, and CI/CD practices.

Earlier I built a regional Vineyard Association app that improved traffic and sales, implemented CoreData persistence, geofencing with MapKit, push notifications, and native SwiftUI components. I collaborate closely with product and design to iterate and deliver impactful user experiences.
