Hi, A full redesign of an existing app requires care to improve the UI without breaking current flows. Since you already have complete source code and no feature changes, I’d focus on clarity, consistency, and polish while preserving every action, state, and navigation path. My approach: - Review current screens and component structure - Build a clean, consistent design system - Redesign key flows in Figma - Implement the new UI in Flutter screen by screen - Test thoroughly for visual and functional consistency Relevant experience includes UI/UX redesign, Flutter implementation, reusable component systems, and responsive app styling. I can start by auditing the app and mapping the redesign, then move into implementation once the direction is approved. Timeline: I can begin immediately and share the first audit/design direction quickly after review of the existing app. One question: should the app structure and navigation remain exactly the same, or are small layout improvements within screens acceptable?

Hey there, Your existing app already has the functionality in place, so the key focus is creating a modern UI/UX system and implementing it without disrupting current features. I can redesign the screens, build a consistent design language, and integrate the approved visuals directly into your existing codebase. I’ll approach this with Figma-based design planning, reusable components, and careful frontend updates to maintain stability across the app. A component-driven redesign will also make future UI improvements faster and easier to manage. Is the existing app built with Flutter, React Native, or native iOS/Android? Looking forward to collaborating with you.

Hi, redesigning an existing Flutter app's UI/UX in Figma and implementing it directly in the codebase without touching functionality is exactly the kind of work I enjoy. My approach: first review your current screens and Dart/Flutter structure, then design a modern, consistent design system in Figma covering all screens, get your sign-off, and implement it as clean, maintainable widget/theme changes. I'll ensure every existing feature keeps working exactly as before, then test thoroughly across devices after implementation. I have strong Flutter and Figma experience, pay close attention to detail, and communicate progress clearly at each stage. Happy to share past redesign work and discuss your current tech stack and screen count before starting. Regards, Harsh Thoriya

Hi there, You already have a working Flutter app and you only want a full UI/UX redesign, then the same features wired back in with the new visuals. That’s exactly the kind of work I’ve done: keep logic untouched, rebuild screens around a consistent design system, and then implement it cleanly. I’ll start by mapping the current screens, then create Figma layouts and components, including navigation, spacing, typography, and states. Once you approve, I’ll update the Flutter widgets to match the design, adjust theming and reusable components, and run through the app to confirm every existing flow behaves the same. I’m available to start this week, with the first Figma pass in a few days. Slavko
