What to look for in a Kotlin freelancer
A strong Kotlin developer should understand the language and the Android platform in depth, not just wire up layouts. Look for:
- Solid Kotlin fundamentals: coroutines, flows, null safety, and idiomatic style.
- Experience with Jetpack and Compose, or a clear reason for the tools they choose.
- Awareness of Android fragmentation: screen sizes, OS versions, and device performance.
- Attention to architecture: MVVM, clean separation, and testable code.
- A portfolio of shipped apps on Google Play, not just tutorials.
Ask for links to apps on Google Play and how they handled testing across different devices. It reveals real production experience fast.
