I’m ready to push our current travel-booking application to the next level and need a mobile developer who can own the entire build for both Android and iOS. The core features we already rely on—polished UI, seamless payment gateway integration, and real-time live tracking—must stay intact, but I’m looking for fresh eyes to refine them and expand the app’s capabilities. What I need from you • Rebuild and enhance the Android codebase while creating a parallel iOS version using the same REST/GraphQL endpoints. • Integrate Google Maps API to power location search, route plotting, and live driver tracking. • Tighten payment processing (currently Stripe) and ensure transactions remain secure and PCI-compliant. • Optimize performance: reduce load times, improve caching, and handle real-time data updates via Firebase or another cloud database you’re comfortable with. • Prepare every release for smooth Google Play Store and App Store submission, including screenshots, descriptions, and compliance items. • Collaborate with our designer for pixel-perfect UI, and coordinate with the backend team so new endpoints roll out in step with your sprints. Acceptance criteria 1. Both Android and iOS builds pass internal QA, unit tests >80% coverage, and UI tests on real devices. 2. Google Maps API functions: location search <1 s average latency, route polyline accuracy within 5 m. 3. Payment flow completes in ≤3 taps, returns success/failure callback, and logs securely in Firebase. 4. Live tracking refreshes every 2-3 s without crashing on poor networks. 5. Apps published to TestFlight and internal Play track with zero blocking store review issues. Nice to have but not required: social login, in-app messaging, or multi-currency support—flag if you can tackle any of these. I prefer someone with at least 1–3 years of proven mobile development, fluent in Kotlin/Java and Swift/SwiftUI (or React Native/Flutter if you can guarantee native-level performance). Clear communication and reliable sprint delivery are non-negotiable. Send over a concise proposal highlighting similar travel or real-time data apps you’ve shipped, the tech stack you’d pick, and an estimated timeline for an MVP upgrade plus iOS parity. Looking forward to working with you.
