Flutter Developer / Full-Stack Developer — East Africa On-Demand Artisan Marketplace

I am looking for an experienced developer or development team to build an on-demand home-services marketplace for the Kenyan market. The concept is similar to Uber, but instead of transporting passengers, customers will request verified artisans/fundis for home and business services such as plumbing, electrical work, carpentry, painting, welding, appliance repair and other services. ### Required platforms 1.⁠ ⁠Customer mobile application 2.⁠ ⁠Artisan/Fundi mobile application 3.⁠ ⁠Web-based admin dashboard 4.⁠ ⁠Backend/API ### Core customer features •⁠ ⁠Phone/OTP registration •⁠ ⁠Location/GPS •⁠ ⁠Service categories •⁠ ⁠Nearby fundis •⁠ ⁠Immediate or scheduled bookings •⁠ ⁠Job posting with description •⁠ ⁠Photo/video upload •⁠ ⁠Fundi quotations •⁠ ⁠Fundi profiles •⁠ ⁠Ratings and reviews •⁠ ⁠Real-time chat •⁠ ⁠Push notifications •⁠ ⁠Job status tracking •⁠ ⁠Map/location tracking •⁠ ⁠M-Pesa payments •⁠ ⁠Receipts •⁠ ⁠Dispute/reporting system ### Core fundi features •⁠ ⁠Registration •⁠ ⁠ID/profile verification •⁠ ⁠Skill/category selection •⁠ ⁠Service area •⁠ ⁠Availability/online status •⁠ ⁠Job requests •⁠ ⁠Accept/reject jobs •⁠ ⁠Submit quotations •⁠ ⁠Chat with customers •⁠ ⁠Navigation •⁠ ⁠Job status updates •⁠ ⁠Before/after photographs •⁠ ⁠Earnings dashboard •⁠ ⁠M-Pesa withdrawal •⁠ ⁠Ratings and reviews •⁠ ⁠Portfolio ### Admin dashboard ⁠ ⁠User management •⁠ ⁠Fundi verification •⁠ ⁠Job management •⁠ ⁠Payments •⁠ ⁠Commission management •⁠ ⁠Disputes/refunds •⁠ ⁠Categories •⁠ ⁠Promotions •⁠ ⁠Notifications •⁠ ⁠Analytics •⁠ ⁠Reports •⁠ ⁠Account suspension/blocking ### Technical preference Flutter for mobile applications, with a scalable backend and PostgreSQL database. Developer may recommend an alternative architecture with justification. Experience with Google Maps, Firebase notifications, M-Pesa/Daraja API, real-time chat and location tracking is strongly preferred. ### Important I do not want a template/demo application. I need clean, maintainable source code that I own, with proper documentation and deployment instructions. The project will be delivered in milestones, with testing and acceptance at each milestone. Developer must provide examples of similar marketplace/on-demand applications already launched.
