In an earlier article, I shared hands-on practices for building a cross-platform application using Kotlin Multiplatform (KMP) and Server-Driven UI (SDUI). We built a simple application where the UI layout is fully controlled by the server, allowing Android and iOS experiences to evolve simultaneously without requiring frequent App Store or Play Store releases. In this article, we will extend that application by implementing end-to-end observability, enabling us to monitor both mobile and server-side behavior in a single pane of glass using OpenTelemetry.

Over the years, I’ve written about interoperability and why it is essential for enterprise systems that must cross technological and business boundaries. Enterprises applications rarely live in isolation. They integrate across platforms, stacks, and ecosystems. Without proper planning, maintaining multiple platforms and technology stacks quickly becomes expensive and complex. This challenge becomes even more evident in cross-platform mobile development. I have previously explored solutions like Unity, PhoneGap (Now Cordova), React Native and Titanium.
