Hire the Best Flutter Developers
in Ukraine

🌿 🌿 🌿 Welcome! I am a professional Flutter Developer with over 4 years of dedicated mobile experience, backed by a strong foundation of 10+ years in Full-stack development.

Senior Flutter developer, 7+ years and 30+ shipped apps. I work on real-time and media: WebRTC, live streaming, Smart TV, gRPC and WebSocket - the parts of an app that break in production, not in the demo. Video calls that survive a weak network. A stream that does not stall. A TV app that behaves on a remote. The hard part is never the happy path - it is reconnection logic, state sync, and the edge cases that only show up on someone else's hardware. REAL-TIME AND MEDIA - WebRTC - video and audio calling, including end-to-end encrypted calls - Video streaming and playback - ExoPlayer, media pipelines, VOD and live - Smart TV - Android TV and Fire TV, remote-first navigation - Real-time data - gRPC/Protobuf streams, WebSocket, Socket IO - Audio streaming - my first production project, back in 2019, was an online radio app FLUTTER From architecture to store release: - Multi-package monorepos and Clean Architecture - BLoC/Cubit, Provider, MobX, GetX - chosen per project, not per habit - Mobile, TV and desktop from one codebase - Native platform channels in Kotlin and Swift when Dart is not enough - Freezed, Retrofit/Dio, Hive, Firebase, GraphQL, CI/CD BEYOND THE CLIENT SIDE - Java / Spring Boot - multi-module services, features, PRs, production debugging - Go and Rust - services and video tooling SYSTEMS AND C++ I maintain a native macOS port of a 2003 C++ game engine: custom Apple Metal renderer, native ARM64, and a dual-build setup that keeps cross-platform multiplayer deterministic by reconciling x87 extended precision down to IEEE 754. Live player base - 45 players and 4,800+ tracked events in the first 18 days after I instrumented the launcher. Built with heavy AI assistance, which is how I approach large legacy codebases. OPEN SOURCE Verified publisher on the official Dart package registry - 5 packages, ~1.6k downloads: a camera plugin, an autocomplete widget, a base kit and a Freezed formatter. HOW I WORK I am opinionated about architecture. If a shortcut will cost you later, I say so before writing it. - SOLID and DRY as working rules, not slogans - no god objects, no spaghetti - Small methods and early returns instead of deep nesting - Naming and structure carry the meaning; if code needs a comment to be understood, it gets refactored - Consistent layering, so the next developer finds things where they expect them - Written updates and clear PR descriptions Send me your project details and I will tell you honestly whether I am the right fit and how I would approach it.

I help businesses build production-ready Flutter apps with smart AI features that actually improve user experience. I specialize in Flutter mobile development for Android and iOS, focusing on clean architecture, scalability, and predictable delivery — not just prototypes. In addition to classic mobile development, I integrate AI-powered features into apps, such as: • AI chat and assistant flows • Smart recommendations • Content generation • AI-based user interaction logic • API-based AI integrations (OpenAI and similar services) Although my Upwork profile is new, I already have real hands-on experience building Flutter applications outside the platform, including fintech, education, health, and AI-driven products. What you get when working with me: • Flutter apps with Clean Architecture • Firebase backend (Auth, Firestore, Functions, Analytics) • AI feature integration via APIs • Payment and subscription flows • Pixel-perfect UI from Figma • Clear communication and regular updates I’m a good fit if you need: – a Flutter app with AI features – an MVP with smart user interactions – a reliable developer who owns the result Feel free to message me — I’m happy to discuss your idea.

Over the last 15 years, I have been a passionate Flutter Developer and Mobile App Developer. I know how to tame development chaos and deliver projects on time. How to coordinate developers and clients. What is important and what is a waste of time and money. My experience: - 15+ years in software development. - Last 6 years main focus: Flutter app developer. Before switching to Flutter Stack, I worked as a native mobile app developer (iOS, Android) and a React Native developer. Мy experience also includes low-level things like BLE, Image processing, and ARKit. I am not scared of diving into native development if required, and writing some Swift, Kotlin, Java, or even Objective-C. I started my career when the first smartphones came out, when iOS Development and Android app development were hell. Besides being a Flutter Developer, I am a Full Stack Developer too. This experience helps when you need to integrate your beautiful Flutter App with a complex backend and implement sophisticated flows for your processes. I can implement push notification with Flutter Firebase Cloud Messaging, payment flow with Stripe, or RevenueCat. Email with SendGrid, Mailgun etc. Real-time chats with Flutter Firebase Cloud Storage, or with a custom ASP.NET solution that features Redis and PostgreSQL. As a Full Stack Developer, I can also implement support of real-time geolocation features in your app. For backend, I prefer ASP.NET Core with C#. But I have experience with Node.js, Go, and PHP, Laravel. And if you really need that, I can even implement a backend on WordPress. Firabase is also an option, but there are caveats that we need to discuss before you choose this technology. That I am a Flutter Developer doesn't mean that I can't do a nice web page for the app on Next.js, or an admin dashboard on React. Almost every mobile app that is more complicated than a to-do list requires some kind of backend and admin dashboard for it. As a Flutter Developer, I published a lot of mobile apps in the App Store and the Play Store. During the publishing process, you need a lot of supporting things, like a website with a privacy policy and a contact us form. I can help with this, too, and do them using React, Next.js, or WordPress. One of my unique points is that I combine Flutter Developer and Mobile App Development experience with Computer Vision specialist skills. This allows me to integrate your latest models directly into the mobile app, avoiding common pitfalls. And make them robust and perform well even on a slow smartphone. Last few years, I worked as a Full Stack Developer and Flutter Developer for Allimb AI startup, and we successfully released the app in production. And now hundreds of patients use it every day. My responsibilities were mobile app development for a Flutter App and implement an ASP.NET Core backend. And supervise the work of AI experts who implemented exercise-specific models on Python and Dart. I helped to bridge a gap between Python algorithms and scripts used to train CV models, and their adoption as Dart code into a Flutter App. For Web Development, I prefer to use TypeScript over JavaScript, React over Angular, and Tailwind over writing CSS. But if needed, I can go vanilla JavaScript, CSS, and HTML. In general, developers often promise a lot, but deliver a little. If you are tired of false promises, developers that require a lot of hand-holding, and failed estimates. I am your new Flutter Developer. I will never promise what I can't deliver. You will always know what you can count on. I love Flutter and love to be a Flutter Developer. It started as mobile app development, but now I also deliver desktop apps, web applications, and robust backends. I stopped working with FlutterFlow; with AI power, it's easier to use Flutter directly. With Love, Your Flutter Developer
