Freelance Android & Kotlin Multiplatform Development

Android expertise. A practical route to Android and iOS.

You need an app built, an existing product moved forward, or someone who can take ownership of the difficult parts. I work with Android and Kotlin Multiplatform teams on implementation, architecture and connected-device integrations.

Where I can help

For product teams adding senior capacity, rebuilding an interface or deciding which parts of an Android and iOS product should share code.

Android delivery

Build features in Kotlin and Jetpack Compose, work through integration problems and support the team through review and release.

Kotlin Multiplatform

Assess what is worth sharing, integrate shared code with platform-specific behaviour, and build interfaces with Compose Multiplatform where it fits the product.

Connected products

Work through BLE communication, device state and the boundary between an app and the hardware it controls.

A manageable first step

Start with the product, the platforms and the part that needs help. I’ll review the existing setup with you and agree a first piece of work: a feature, an integration or a technical assessment. For an existing team, we can work within your review and delivery process.

Before we start

Can you join an existing team?

Yes. Work can cover hands-on development, code review and technical guidance alongside your developers and designers.

Do we need to move everything to KMP?

No. We can assess a specific shared module or feature first. Platform requirements and maintenance costs should drive that decision.

Where do you work?

I’m based in Germany and work in English and German, mostly remotely. Onsite visits and workshops can be discussed as part of the engagement.

Tell me where you need help.

Tell me about your product, target platforms and the work you need help with. If there’s an existing codebase, a short description of its current state is enough to start.
