The Kotlin/Wasm based Compose for Web browser debugging capability that @sebi.io demoed below is very nice (kotlinlang.org/docs/whatsne...). Showing example here in ClimateTrace KMP/CMP sample (github.com/joreilly/Cli...).

Still looking for a job. I'm leaning to things like intersection of native and JavaScript, runtimes, developer tooling, browsers, WebAssembly, web security.
