Flutter Mobile App Developer | Figma UI/UX Design
We had a great experience working with Web Design Sun on our mobile app project. Their team delivered both Flutter mobile app development and Figma UI/UX design, and the quality exceeded our expectations.
From the beginning, they showed a strong understanding of our requirements and translated our ideas into a clean, modern, and highly intuitive design. The Figma designs were well-structured, visually appealing, and user-focused, which made the development phase smooth and efficient.
On the development side, their Flutter expertise was clear. The app is fast, responsive, and works seamlessly across devices. They paid attention to performance, scalability, and overall user experience, which is exactly what we were looking for.
Communication was consistent and professional throughout the project. They were responsive, open to feedback, and always willing to go the extra mile to make improvements.
Overall, we’re very satisfied with the outcome and would highly recommend Web Design Sun to anyone looking for reliable Flutter development and high-quality UI/UX design.

Mobile App Developer Needed for Social App UI Prototype (Swift and Kotlin)
We had a fantastic experience working with Igor and his team at Web Design Sun. They are highly skilled Flutter mobile app developers who delivered exactly what we needed. They worked on a very sharp timeline, completing tasks even ahead of the deadlines, and successfully achieved our project goals on time as promised. The app they created is of excellent quality and is now live on both the Apple App Store and Google Play Store. We are extremely satisfied with their work and would be happy to collaborate with them again on any upcoming projects. Highly recommended!

WHY A FULL BUILD, NOT A PATCH
I take on complete projects rather than isolated tickets. Whether you are launching a new product, modernizing an app that is already live, or scaling after your first real users arrive, the target is the same: one codebase your team can keep shipping on for years, running on iOS and Android, without paying twice to maintain two native apps. You hire one developer who owns it from scope to store release.
WORK I CAN POINT TO
CardRight, a mobile app live on both iOS and Android.
jewbuzz.love, a Flutter dating app I built and published to the App Store and Google Play.
A chat app built in Flutter with a Node.js backend and a React admin panel.
A trading app for a crypto exchange.
An app design taken from Figma through development to release, on a contract closed at 5.0.
🎯 WHAT I DO
- Flutter app development for iOS and Android from a single codebase
- Cross-platform mobile app development in Flutter and Dart, with native Swift or Kotlin where a platform feature needs it
- MVP development for startups, scoped so version one reaches real users instead of stalling in scope creep
- Figma designs built into production screens, not approximated
- Subscription and SaaS mobile applications, including In-App Purchases and RevenueCat
Chat, messaging, social and dating apps
- AI features inside your app, wired to your model through your API
- API integration and backend connectivity: REST APIs, GraphQL, Node.js, Laravel
- Firebase and Supabase integration, authentication and push notifications
- Stripe payments, Google Maps, analytics and Bluetooth device connectivity inside your app
- App Store and Google Play deployment, review responses and release management
- Performance optimization, refactoring and long-term maintenance of an existing app
- QA and testing on physical iOS and Android hardware
💼 WHO I WORK WITH
- Founders who need an MVP built and published, then iterated on with real user feedback
- Companies with an app already live that has outgrown its first version and needs a rebuild
- Teams maintaining separate iOS and Android codebases who want to consolidate onto Flutter
- Product owners who need one developer to own the whole build, from the first screen to the store listing
- Businesses that need an internal tool on mobile, connected to the systems they already run
- Founders who inherited a half-finished app from a developer who stopped replying
I am not the right fit for a single-screen tweak, an unpaid test task, or a project with nobody available to make product decisions.
🔄 HOW I PROPOSE TO RUN YOUR BUILD
This is the order I work in on a full engagement:
First, scope and architecture. You and I agree what version one actually contains, and I map the architecture, the data model and the integrations before any screen is built. This is also where I tell you what to cut. Most version ones I am handed are two releases pretended into one.
Then the build, in increments. What you get is a running build you can open on your own device rather than a status update at the end of the month.
Integrations along the way. Firebase or Supabase, authentication, payments, push notifications, maps, analytics, and whatever API the app depends on.
Testing on physical iOS and Android devices, not only the simulator.
Then store submission. I prepare the release builds, the listing assets and the privacy declarations, then handle App Store and Google Play review until the app is live. This is the step most half-finished apps never get past, and the one clients underestimate: privacy declarations, tracking disclosures, and a rejection that has to be answered rather than argued with.
After launch, support. OS updates, Flutter and SDK upgrades, and the changes your first users ask for.
You keep the full source, the repository, the store accounts and the backend credentials. No lock-in.
📞 NEXT STEP
Send me your app idea, your current build, or the codebase you inherited, and tell me what you want live and by when. I will come back with the architecture I would use, an honest scope for version one, and a delivery timeline for iOS and Android. If Flutter is the wrong tool for what you are building, I will tell you that, before you hire me to build it in Flutter anyway.
