OLX-Style Marketplace Website & App

I’m building a classifieds marketplace modelled on OLX India and need end-to-end development for both a responsive website and companion mobile application(s). The platform must allow two kinds of users—buyers and sellers—to interact seamlessly through intuitive product discovery and secure communication tools. Core features I absolutely need: • Product listing and browsing with robust search and category filters • In-app messaging so buyers and sellers can negotiate without leaving the platform • User reviews and ratings to build trust and transparency In addition to those essentials, please include user registration/login (social and email), a clean dashboard for each account type, and an admin panel where I can manage listings, users, and reported content. I’m open to your recommendation on the tech stack for both web and mobile; whether you suggest native iOS/Android, Flutter, React Native, or another proven approach, explain why it fits a fast, scalable marketplace. Deliverables: 1. UI/UX designs approved before development begins 2. Fully functional website and mobile app builds, tested and ready for launch 3. Source code with clear documentation 4. Deployment support to my hosting and the app stores Please share examples of similar marketplace or e-commerce projects you’ve delivered, your preferred stack, and an estimated timeline broken into logical milestones. I’m looking for a clear plan that shows how you’ll meet the core requirements above while ensuring performance, security, and a smooth user experience.
