Great mobile experiences have become an expectation – so much so that businesses that aren't meeting this expectation are teetering on the edge of the dustbin of history. What's less obvious is the how: only recently has the community started consolidating around the best practices of architecting mobile apps. Still, developers find themselves navigating many unanswered questions alone. To further complicate, the rise of newer technologies powered by a worldwide rollout of 5G – AR/VR/MR, Machine Learning & AI, IoT, and Crypto – will necessitate new approaches altogether. In this session, we will discuss delightful user experience creation, common development approaches, the impact of emerging technologies, and the importance of properly synchronized local data. You'll learn how MongoDB, Realm, and Atlas Device Sync are uniquely designed to make building great mobile experiences efficient and future-proof.
