School Transport & Child Journey Tracking POC

Project: School Bus Tracking & Child Journey Tracking – MVP/POC I am looking for a developer to build a very small functional POC for a school transportation tracking system. This is not the full production application. The POC will be tested on 1 school bus with approximately 20–30 students. Required features: 1. Conductor/Driver Interface Simple login Select/start a bus trip Display the list of assigned students Conductor can tap a student's name to mark them as "Boarded" Record the exact boarding time Option to mark the trip as started/ended 2. GPS Tracking Use the Android phone's GPS to track the bus Location should continue updating when the app is minimized/phone is locked Send location periodically to the backend Basic handling of temporary internet/network loss 3. Parent Interface Simple mobile-friendly web page or lightweight app (no need for a polished production app) Parent can see their child's current bus status Live bus location displayed on a map Show approximate ETA to the selected/home bus stop 4. Notifications When the conductor marks a child as boarded → parent receives "Your child has boarded the bus." When the school/return trip starts → parent receives notification Basic ETA/approaching notification 5. Basic Backend Student records Parent accounts Bus/route information Trip records Boarding events Live GPS location Technical preference: Android for the conductor side Flutter is acceptable if appropriate Firebase/Supabase or another lightweight backend is acceptable Google Maps API or equivalent for maps Please use existing APIs/services rather than building infrastructure from scratch. Important: This is a proof of concept, so I don't need: RFID Payments Face recognition Complex school ERP Advanced admin dashboard iOS application Fancy UI/animations The priority is reliable GPS tracking, live map, boarding status, ETA, and notifications. I am technically knowledgeable and will provide the product requirements. Please quote a fixed price and estimated delivery time for this exact scope. Also, please mention if you have previously implemented Android background GPS/location tracking, as this is the most important technical requirement
