Mobile App UI/UX Designer

Seeking a skilled designer to create a user-friendly interface for a community travel marketplace app. Responsibilities include designing intuitive screens, crafting a seamless user experience, and ensuring visual consistency across the app. The ideal candidate will have experience in mobile app design and a strong portfolio showcasing previous work. I'm looking for an experienced UI/UX designer to design a modern, clean, and premium mobile application. This is not a traditional courier app. The platform connects people who are already traveling between cities with people who need something transported, such as homemade food, small packages, documents, or items from another city. The primary focus of the design should be trust, simplicity, community, and a premium user experience. Main User Types Travelers Travelers can: Post upcoming trips Browse transportation requests Submit offers (bids) Chat with requesters Complete deliveries Receive ratings and reviews Requesters Users can: Post transportation requests Request homemade food from family Request someone to bring an item from another city Request transportation for small packages or documents Compare offers from travelers Choose a traveler Chat Leave ratings and reviews Initial Features Splash Screen Onboarding Login / Registration Home Dashboard Post Trip Browse Trips Post Request Browse Requests Trip Details Request Details Bid Screen Chat List Chat Screen Notifications User Profile Ratings & Reviews Settings Approximately 20–25 mobile screens. Design Style The application should feel: Modern Premium Minimal Friendly Clean Trustworthy Please use proper spacing, typography, reusable components, Auto Layout, and create a scalable design system suitable for Flutter development. I value designers who pay attention to details more than those who simply send generic proposals. If you've read this description carefully, please begin your cover letter with IRAP before writing anything else. It helps me identify applicants who actually understand the project requirements. Deliverables Complete Mobile UI/UX Figma Source File Design System Color Palette Typography Components Auto Layout Interactive Prototype What I'm Looking For Please apply only if you have experience designing modern mobile applications. When applying, please include: A short introduction about yourself. Links or screenshots of your best previous mobile UI/UX projects (Figma, Behance, Dribbble, or similar). Please don't send your entire portfolio—share the projects you believe best demonstrate your design quality. Your estimated timeline. Your fixed-price quote. I'm looking for someone who can think beyond beautiful screens and design an experience that feels trustworthy, intuitive, and enjoyable for everyday users. I'm planning to build a long-term product, so if we work well together, there may be opportunities for future design work as the application grows. Original Work Requirement Please submit only your own original portfolio work. I carefully review portfolios for authenticity, and I may ask follow-up questions about your design process or request supporting Figma files for shortlisted candidates. If I determine that a portfolio contains work that has been copied, falsely represented, or presented as your own when it is not, I will end the interview process immediately and may report the matter through Upwork if it appears to violate their policies. If you're a genuine designer with original work, you have nothing to worry about—I value honesty and long-term collaboration much more than an exaggerated portfolio. Final Note You will find two questions in this job post. Please answer both of them along with your proposal. Please answer them honestly and in your own words. I value genuine thinking and real experience much more than perfect English. A simple, honest response is far more valuable to me than a polished or AI-generated one. I'm looking for a long-term design partner, so authenticity, attention to detail, and honest communication are qualities I value highly.
