Cross-Platform Mobile with Kotlin Multiplatform

One Kotlin codebase, natively compiled for Android, iOS, and Web with Compose Multiplatform. Real native performance and real code sharing — not a WebView wrapped in an app icon.

What this covers

Most freelance developers offer either native (separate Android + iOS codebases, double the cost) or a JS-based cross-platform framework. Kotlin Multiplatform is a third option most can't actually deliver: native compilation on every platform, sharing business logic, networking, and UI through Compose Multiplatform — while still dropping into platform-specific code wherever it's genuinely needed.

  • Shared business logic: data layer, networking (Ktor), and state management shared across platforms — not rewritten three times.
  • Compose Multiplatform UI: one UI codebase rendering natively on Android, iOS, Desktop, and Web.
  • Native where it matters: platform-specific APIs (camera, BLE, notifications) still get proper native implementations, not lowest-common-denominator shims.
  • Migration path: if you already have a native Android app, this can mean migrating incrementally rather than a full rewrite.

Representative work

EVA2Z Connect / FleetA2Z

Live on Play Store

GPS/EV-tracking app migrated from a native Android-only codebase to Kotlin Multiplatform, achieving ~85% code sharing between Android and iOS — while cutting APK size from 81.6MB to 20–25MB and fixing Play Protect blocking issues, with PhonePe payments integrated.

WayGo — Fleet & Transport SaaS

Personal project

The strongest proof point for this service: a B2B SaaS platform built with Compose Multiplatform targeting Android, iOS, Desktop, and Web from a single MVI-architected codebase — 42 production screens across 4 user roles, built solo.

Why this matters for you

Fewer codebases means fewer places for platform-specific bugs to diverge, a faster path to feature parity across Android and iOS, and a meaningfully lower cost than maintaining two fully separate native teams — without the compromises that come with a JS-based cross-platform wrapper.
