When to hire a Fractional Kotlin Developer
Hire a Kotlin Developer when your Android or JVM backend work is stalling and your current team lacks the senior Kotlin depth to unblock it.
Your Java Android codebase is aging
Half the app is still Java with XML layouts, and nobody on the team has led a staged Kotlin and Compose migration without breaking releases.
Crashes and ANRs keep climbing
Play Console vitals are red, and the root causes trace back to misused coroutines, lifecycle bugs, or blocking calls on the main thread.
Your mobile lead just left
Releases are queued, the build pipeline is fragile, and you need someone who can own the Android app while you decide on a permanent hire.
You want one codebase for iOS and Android
You are weighing Kotlin Multiplatform for shared business logic but need someone who has shipped it to production to tell you what to share and what to keep native.
Your Spring or Ktor services need Kotlin expertise
Backend engineers are writing Java-style Kotlin, and you need someone to set conventions for null safety, coroutines, and testing on the JVM.
The benefits of hiring a Fractional Kotlin Developer
You get a senior Kotlin engineer working in your repo within days, scoped to the Android or backend work you actually need done.
Put a senior Kotlin engineer on your Android app
Bring in someone who has shipped production Kotlin at scale for a monthly retainer, instead of carrying a senior mobile salary and benefits package year round.
Start the Compose migration this sprint
We match you in about 3 days, so the engineer can be reading your Gradle setup and module graph while a traditional search is still screening resumes.
Fix coroutine leaks with proven Kotlin experts
Every operator is pre-screened by veteran executive recruiters on shipped apps, references, and hands-on work with coroutines, Flow, and dependency injection.
