Cost savings calculator
Move the slider to compare a senior US Kotlin team with an India-based team of the same size. Price depends on seniority, US overlap and whether you hire one developer or a pod.
A planning estimate: $90 an hour onshore and $32 offshore, 160 hours per person each month. Not a JumpGrowth quote. Final cost follows seniority, overlap and scope.
US onshore at $90/hr

per month
Offshore at $32/hr

Step 01Kotlin developer case studies / 01
Native Android products in the public portfolio, the platform hired Kotlin developers ship on. Open a study for the brief, platform and stack.
Kotlin developer client stories / 01
Clients who shipped mobile products on Android, the platform hired Kotlin developers work in.
Security products leave no room for guesswork. The team shipped a companion app our customers trust from the first unlock.
01How do I hire Kotlin developers for my team?
Hire Kotlin developers to build Android apps, Multiplatform modules and Ktor or Spring Boot services in your stack. Embed one engineer in your team or add a Kotlin squad. You interview the shortlist and choose who joins.
02What Kotlin skills can we hire for?
Kotlin architecture, Android with Jetpack Compose, coroutines and Flow, Kotlin Multiplatform, Ktor and Spring Boot services, Java migration and testing.
03Can hired Kotlin developers move our Java code to Kotlin?
Yes, a file at a time. Java and Kotlin live in the same module, so the app keeps shipping during the move.
04Is Kotlin Multiplatform ready for production?
For shared logic, yes. They share models, networking and storage, and keep each platform’s interface native.
05Do they write server code too?
Yes: Ktor or Spring Boot services in Kotlin, sharing models with the apps where that helps.
06How do they keep coroutines predictable?
Structured concurrency with clear scopes, and tests that control virtual time, so async code behaves the same every run.
07Can we embed Kotlin developers in our team or hire a pod?
Both. Add one Kotlin developer through staff augmentation, or pair Kotlin engineers with a dedicated delivery pod when you need apps and release in the same team.
08What affects the cost of hiring Kotlin developers?
Seniority, US workday overlap, and whether you hire one developer or a pod. The planner on this page uses a $90/hr onshore and $32/hr offshore planning rate, 160 hours a month. It is an estimate, not a JumpGrowth quote.
09Is this staff augmentation or a managed delivery team?
Both. Add one Kotlin developer, a small team, or a full pod with its own lead.
10Can we start with one Kotlin developer?
Yes. Most teams start with one Kotlin developer in a clear gap and add people once the fit is proven.
11Can we interview Kotlin developers before we choose?
Always. You see the profiles, run your own interviews and make the final call.
12Can we scale the team after the first Kotlin developer starts?
Yes. Add people as the roadmap grows, or move from one Kotlin developer to a managed pod with its own lead.
