InfluxDB
Power Real-Time Data Analytics at Scale. Get real-time insights from all types of time series data with InfluxDB. Ingest, query, and analyze billions of data points in real-time with unbounded cardinality.
Sharing UI code is definitely feasible though. Look at Redwood for example. It isn't really a general purpose UI library as-is, but someone could (in theory) build a library of cross-platform widgets that work a lot like React Native widgets, and that would enable you to build UI entirely in multiplatform Kotlin.
