I am preparing to launch a local food-delivery service in Sivakasi, Tamil Nadu and need a full, ready-to-deploy software package. The scope covers four distinct components that must work seamlessly together: • Android Customer App – a minimalistic, fast interface focused on quick browsing, cart, OTP login and checkout. • Delivery Partner App – Android build with a detailed earnings dashboard, live order flow, real-time location tracking and metrics. • Restaurant Web/Tablet Panel – order intake, status updates, delivery assignment and basic menu tools. • Admin Panel – end-to-end control of vendors, users, delivery partners and operational settings. Key features I must have from day one • Secure OTP login for every user type • Delivery-charge slab control that I can update without code changes • Commission control for each restaurant • Service-radius toggle, initially fixed at 15 km • Push notifications across all roles (FCM preferred) • Full, unencrypted source code with build instructions and database schema Tech flexibility is welcome, but please keep the stack mainstream (Laravel, Node, Firebase, Flutter, Kotlin, React Native, etc.) so future maintenance is straightforward. When you reply, include: 1. Play-Store/Test-Flight or APK/URL demo links for each module 2. Delivery timeline and total cost broken into milestones 3. Post-launch support terms (bug fixes, minor enhancements) I will shortlist only those who provide a working demo along with clear pricing and support details.
