Hi, I'm Ogiński

Apps that feel native, on every screen.

Let's work together

React Native developer shipping iOS & Android apps - going native with Swift when the product calls for it.

(01) About

Shipping pixels to pockets for 5+ years.

I'm a mobile developer focused on React Native, reaching for native iOS in Swift and SwiftUI when a product needs it - with 5+ years of commercial experience in mobile and web. I own features end to end: building them, stabilising production apps, and shipping releases to the App Store and Google Play. My background in React and pixel-perfect front-end work means I turn designs into polished, consistent mobile UI.

    Mobile Developer

    Euvic S.A.

    I rewrote a production React Native app onto a modern stack with a clean, layered architecture - a new API and domain layer, TanStack Query and Zustand - cutting Sentry errors 3x. On iOS, I ship new features and user flows in an offline-first SwiftUI app I took over from previous developers. I also run iOS and Android releases from testing to store publication, join estimation and client meetings, and prepare AI-assisted POCs and MVPs for clients.

    Freelance

    I built new features and fixed interface issues in an iOS app, refactored navigation to the Coordinator pattern, and migrated it from UIKit storyboards to SwiftUI, replacing closure-based navigation.
