Android • Kotlin • Jetpack Compose • .NET

Shipped software. Modernized codebases.

I’m Rachelle Timm—an Android and .NET engineer focused on reliable delivery and legacy-to-modern migrations (Kotlin/Compose, MVVM).

What I bring

Engineering that keeps shipping

Pragmatic improvements that modernize codebases without slowing teams down.

Legacy-to-modern migrations

Upgrade older codebases to Kotlin/Jetpack Compose and MVVM while keeping delivery moving.


Shipped app experience

Hands-on delivery of production features in consumer apps and enterprise environments.


Maintainable architecture

Incremental refactors that improve testability, readability, and onboarding.


Cross-platform & cloud background

.NET, Azure DevOps, and Xamarin.Forms experience for teams spanning mobile and cloud.

Capabilities

How I can help

From modern Android work to backend support, I focus on clean architecture and predictable delivery.

Android engineering (Kotlin/Compose)

Build new features, improve performance, and modernize UI with Jetpack Compose and solid state management.


Legacy modernization & migrations

Move Java/XML screens to Kotlin/Compose, introduce MVVM, and reduce tech debt without big-bang rewrites.


.NET & Azure DevOps delivery

Support teams with C# services, CI/CD, and release processes that keep quality high and cycle time low.


Technical consulting & architecture

Code reviews, system design, and delivery planning to de-risk migrations and accelerate execution.
