I am excited about the opportunity to develop a feature-rich and user-friendly marketplace app tailored to your requirements. With experience in building scalable mobile applications for both iOS and Android, I am confident in delivering a secure and efficient platform that enhances user experience while ensuring seamless transactions. The app will include key features such as a secure escrow payment system to protect buyers and sellers, real-time in-app chat for direct communication, a listing system for browsing and managing ads, and location-based search by postal code. Inspired by platforms like Vinted, the UI/UX will be intuitive and user-friendly. Additionally, multilingual support will allow expansion into French and Spanish markets with your assistance in translation. The development approach includes using React Native or Flutter for cross-platform compatibility or native technologies like Swift and Kotlin, ensuring security with OAuth 2.0, biometric login, and encrypted databases. Agile methodologies will be followed for efficient development, testing, and deployment. The estimated timeline is 14-18 weeks, divided into four phases: UI/UX design, backend development, frontend integration, and testing. Budgeting will be competitive, with final pricing depending on the chosen technology stack and customizations. My expertise in marketplace app development, secure payment integrations, and scalable architecture ensures a high-quality solution delivered within the agreed timeframe. I look forward to discussing this project in detail and aligning the development with your vision.

I am excited about the opportunity to develop your marketplace app. With expertise in React Native and backend frameworks like Node.js and Strapi, I can create a secure, scalable app optimized for both iOS and Android. I will integrate a secure escrow payment system using Stripe, enable real-time chat with Firebase, and build a location-based search using the Google Maps API. The user-friendly interface will resemble platforms like Vinted, ensuring a seamless user experience. I can also implement multilingual support in French and Spanish using i18next. I estimate a delivery time of 8–10 weeks with competitive pricing. Looking forward to collaborating!
