Senior mobile engineer — Android · Kotlin Multiplatform · Flutter · React Native
I build cross-platform apps and the developer tools that make them easier to ship. Kotlin and Dart most days, TypeScript and Node.js on the backend.

Kotlin · Compose Multiplatform · WASM
A port of gskinner's Wonderous to Compose Multiplatform — one Kotlin codebase running on Android, iOS, desktop and the browser via WASM. Built to find out how far Compose can be pushed on animation-heavy, art-directed UI: parallax, shared-element transitions and custom illustration work included.

Kotlin Multiplatform · Ktor
An HTTP inspection library for Ktor, in the spirit of Chucker. Drop it into a client and inspect requests, headers and bodies from inside the running app — then go further and override or mock responses without touching the backend. Published on Maven Central for Android, iOS, desktop and web.

Every other Kotlin Excel library wraps Apache POI, which is JVM-only. Kexcel parses and writes .xlsx itself, in pure Kotlin, so the same spreadsheet code runs in commonMain on JVM, Android and iOS — styling, formulas, merged cells and all.
val excel = Excel.createExcel()
val sheet = excel["Sheet1"]
sheet.updateCell(CellIndex.indexByString("A1"), TextCellValue("Revenue"))
sheet.updateCell(CellIndex.indexByString("B1"), FormulaCellValue("=SUM(B2:B12)"))
val bytes: ByteArray = excel.encode()Repository · Documentation · Maven Central
Flutter · Dart · macOS, Windows, Linux
A desktop log viewer for Android and iOS devices, for developers and QA who need device logs without a terminal. adb and libimobiledevice are bundled, so there is nothing to install: multi-device tabs, live filtering, wireless debugging, screen mirroring, iOS crash logs and log import/export.

I started on native Android with Java, moved through Jetpack Compose to Compose Multiplatform, and ship Flutter and React Native alongside it — so cross-platform decisions get made on trade-offs rather than on whichever framework I happen to know.
Open to interesting cross-platform work — say hello.
