I need a mobile application that makes it effortless for clients to book qualified repair technicians straight from their phone. The focus is strictly on household Repairs, and within that niche the app must support the three core service categories: • Plumbing • Electrical • Appliances To give users a smooth end-to-end experience, the build must also include: • Real-time booking system with calendar integration • Secure payment gateway (card and wallet support) • Live job-status and technician tracking A clean, intuitive UI for both customer and technician sides is essential. An admin dashboard to manage service listings, pricing, and user accounts should accompany the mobile release. I am flexible on the tech stack—whether you prefer native iOS/Android, Flutter, React Native, or another modern framework—so long as performance is solid and future updates remain straightforward. Please outline your proposed architecture, estimated timeline, and any similar projects you have shipped. A functional prototype delivered in milestones (MVP → beta → store-ready build) will help keep the project on schedule.
