About the service

I'm a Flutter developer and I create mobile apps that run on iOS and Android simultaneously from a single Dart codebase. Over the past few years I've shipped all kinds of products — from compact MVPs for early-stage startups to large apps with complex business logic, and Flutter consistently lets me deliver a polished, feeling-native result on both platforms without two separate teams and two separate projects. I deliberately work with Flutter, not React Native: Dart's tooling, the widget rendering engine, and the framework's predictability give me precise control over performance, animations, and exactly how the app looks down to the pixel.

My work starts by understanding what the app should do and who will use it, only then do I choose the architecture. I prefer clean layered structure with clear separation of interface, business logic, and data, thoughtful state management, and code the next developer will read without hints. I integrate REST and GraphQL, set up authorization and secure token storage, hook up push notifications, and build reliable offline mode so the app works when there's no connection. Throughout the project I keep you in the loop and send regular builds you can install and test on your device, so there are no surprises at the end.

When the product is ready, I bring it to release: prepare materials for stores, set up signing and profiles, publish to App Store and Google Play. After launch I stay in touch for updates, fixes, and new features, because a released app is the start of its life, not the finish.

What I offer:
— Cross-platform iOS and Android apps from a single Flutter/Dart codebase
— Clean architecture and state management (Bloc, Riverpod, Provider)
— REST and GraphQL integration with secure authorization
— Push notifications, deep links, and offline data sync
— App Store and Google Play publishing, signing and release setup
— Support, updates, and new feature development
