I need a complete bus-ticket booking application built natively for both iOS and Android. The core brief is simple: passengers must be able to search routes, reserve seats and pay from their phone just as smoothly as they would on any top-tier travel app. I’m counting on your expertise to shape the exact feature set and flow, so please send a detailed project proposal outlining: • recommended architecture and tech stack (e.g. Swift/Kotlin with Firebase, React Native, Flutter, or any approach you feel suits this scale) • the booking journey you envision, from route selection to e-ticket delivery • security and payment gateway choices that meet PCI standards • timeline broken into milestones, with clear deliverables for each phase • post-launch support you can provide If you have live links or screenshots of similar apps you’ve shipped, feel free to include them to help me gauge UI quality and performance benchmarks. I’ll review every proposal on clarity, practicality, and how well it anticipates real-world user needs.
