Hybrid Mobile Solutions Architect | Flutter & React NativeViktor Zahurskyi
I build high-performance, cross‑platform mobile apps with Flutter and React Native, delivering native‑like UX on both iOS and Android. I use clean, modular architecture (Bloc/Provider, Redux, MVVM) with type-safe APIs, offline-first data layers, and secure auth to ensure speed, reliability, and scale. With automated testing (unit/widget/e2e), CI/CD (Fastlane, Codemagic, GitHub Actions), and store deployment, I ship polished, production-ready apps quickly and consistently. If you need to accelerate a new build or transform an existing codebase, I onboard fast and deliver measurable results from the first sprint.
What's included
📱 Cross‑Platform App Development
A high‑performance, responsive mobile application built using Flutter or React Native, designed to deliver a seamless, native‑like experience across iOS and Android devices.
🎨 Custom UI/UX Implementation
Implementation of pixel‑perfect designs from Figma, Sketch, or XD, optimized for responsiveness, accessibility, and consistent design systems between iOS and Android platforms.
⚙️ Backend & API Integration
Connection of your app to RESTful APIs, Firebase, GraphQL, or third‑party services, ensuring smooth data synchronization, authentication, and role‑based user flows.
💾 Data Management & Caching
Efficient integration of local storage (SQLite, Hive, or Secure Storage) and cloud databases for real‑time data access, offline usability, and secure user data handling.
🧩 Native Feature Integration
Bridging key native modules (Camera, GPS, Biometrics, Push Notifications, etc.) to offer native‑level functionality while maintaining cross‑platform efficiency.
🚀 App Store & Play Store Deployment
End‑to‑end guidance for publishing on App Store and Google Play, covering signing, versioning, build optimization, and compliance with both Apple and Google requirements.
🛠️ Post‑Launch Support (14–30 Days)
Bug fixes, performance optimization, and minor UI/logic improvements to ensure stable, consistent cross‑platform performance after release.
FAQs
Both are excellent for cross‑platform apps. Flutter is ideal for pixel‑perfect UI, smooth animations, and speed; React Native is best when integrating with existing web or React projects. I’ll help you choose the right framework based on your app’s goals, budget, and tech stack.
Yes. Every app is built and tested for full compatibility on both platforms, delivering native‑level performance and smooth interaction for all devices.
Absolutely. I can integrate REST, GraphQL, Firebase, or custom APIs, enabling real‑time data access, authentication, notifications, and business logic within your mobile app.
Yes. I can integrate AI chatbots, recommendation engines, GPT‑based content features, or automated workflows powered by n8n, Make.com, or OpenAI APIs directly inside your hybrid app.
Yes. I handle end‑to‑end deployment, including signing, store listing setup, review compliance, and managing the approval process on both Apple App Store and Google Play.
Each project includes 14–30 days of post‑launch support for fixes and minor adjustments. For long‑term maintenance or feature upgrades, I offer flexible retainer options.
