I want to bring a new hyper-local logistics app to life for restaurants and grocery stores that runs smoothly on both iOS and Android. The primary goal is to let local businesses tap straight into the ONDC network so their in-house riders—or any delivery partner available in the ecosystem—can pick up and drop orders without friction. To make that happen, the build must cover three concrete pillars: • Integration with ONDC network – full compliance with current APIs and handshake flows. • Notifications from other delivery platforms – the app should surface real-time alerts from services such as Swiggy and Zomato so a rider can grab opportunities beyond our own pool. • Delivery fee calculation & submission – distance-based pricing, surge logic if needed, and automatic fee reporting back to the originating restaurant or ONDC endpoint. Beyond those essentials, the app also needs a fallback: if no rider is available inside our pool, orders should be auto-diversified to the wider network so customers still get served. I’m looking for someone who has already shipped mobile logistics or marketplace solutions and understands how to keep sync stable when multiple third-party feeds are involved. If that sounds like you, tell me about the most relevant projects you’ve delivered, the tech stack you prefer for cross-platform work, and any direct experience with ONDC or similar open commerce standards. Robust code, clean architecture, and clear documentation are non-negotiable—as soon as the core feature set passes acceptance tests, we’ll start mapping the next growth iterations together.
