Hi, Ksenia, can I use any language for backend of the application? I am intending on using Rust. Is that fine?

Hi @Alwin Varghese, the goal of the contest is to explore the Kotlin Multiplatform capabilities. Kotlin works for backend 🙂 If you have your Kotlin app running on different platforms and Rust for backend, as there are some technical limitations to implement it in Kotlin, that’s acceptable. But opting for Kotlin on the backend would give you a competitive edge.
