For expediting your development process, use managed cloud services like Mobile-Backend-as-a-Service (MBaaS) and Platform-as-a-Service (PaaS) platforms. After that, you can go for designing and developing the APIs for implementing the core features. Utilize third-party APIs for other non-core features like push notifications. Overall, build a mobile app that offers world-class user experience, performance, and security.
