Setting up an India-based Kotlin squad
Krapton is a Kotlin development company in India that sets up Android and Kotlin Multiplatform squads in New Delhi for product companies abroad. The squad shape follows the work: Android engineers fluent in Compose and coroutines, an engineer who owns the shared Kotlin Multiplatform module and its Swift-facing API when iOS is in scope, and a QA engineer who tests on a spread of real devices, since Android fragmentation across manufacturers and OS versions causes bugs that emulators miss. A lead reviews every pull request for coroutine scope leaks, main-thread work and nullability shortcuts. The overlap plan is written into the engagement, reserving the IST evening for calls with US product owners and the IST afternoon for UK, EU and UAE colleagues. Release ownership is agreed upfront, so it is clear who signs builds, who presses publish in Play Console and who holds the upload key.
Kotlin development services in India
Dedicated Android Kotlin squads
Compose and coroutines engineers who work from your backlog, follow your module conventions, and join standups in the agreed overlap window with a lead accountable for delivery.
Shared KMP module ownership
An India-based engineer maintains the Kotlin Multiplatform module your Android and iOS apps consume, publishing versioned builds and keeping the Swift API stable for your iOS developers.
Real-device Android QA
Manual and automated testing on phones from several manufacturers, plus Firebase Test Lab runs, catching OEM-specific issues with background limits, permissions and camera behavior.
Java and view modernization
A background track that converts Java classes to Kotlin and XML layouts to Compose, run by the India team while your engineers stay focused on roadmap features.
Kotlin backend support
Ktor or Spring Boot services maintained alongside the app, so API changes, coroutine-based endpoints and mobile releases are planned by one team in one time zone.
Release and store operations
Play Console release tracks, staged rollouts, Android vitals monitoring and target SDK updates handled on a documented schedule, with your team approving each production promotion.
Why an India-based Kotlin team from Krapton
Senior engineers, fixed scope, and code you own — the things agencies promise and rarely deliver.
Vetted on Kotlin, not Java
Interviews test coroutines, Flow operators, Compose state hoisting and sealed classes, so you get engineers who write idiomatic Kotlin rather than Java with different syntax.
Signing keys stay yours
Your company owns the Play Console account and upload key; engineers get scoped roles, and keystores live in your CI secrets rather than on a laptop in New Delhi.
Demos on installable builds
Sprint demos use real builds from Firebase App Distribution or Play internal testing, so stakeholders in any time zone can install and try features themselves.
Contracts written for software
NDAs, IP assignment covering source, Gradle plugins and design assets, and clear exit terms are signed before onboarding, under an agreed governing law.
How we run Kotlin projects from India
01
Interviews and code task
You interview proposed Kotlin engineers and may set a short task, such as turning a callback API into a Flow with tests written in Turbine.
02
Access and onboarding
After contracts are signed, engineers receive repository access, Play Console roles and Firebase project permissions, and the lead documents the module map.
03
Sprints and build reviews
Pull requests pass lint, Detekt and tests in CI, the lead reviews them in New Delhi, and each sprint closes with an installable build demo.
04
Handover and transition
Your developers get module documentation, release runbooks, signing setup notes and paired sessions on the shared Kotlin code before the India team steps back.

Kotlin development in India: questions answered
How does a Kotlin development company in India handle overlap with US and UK teams?
It handles overlap by fixing a shared window per client and doing the rest asynchronously. UK and EU teams usually meet the New Delhi squad during their morning, while US teams meet in the IST evening. Between meetings, pull requests, installable test builds and written sprint notes carry the work, so Kotlin features keep moving without everyone being online together.
What should I check when I hire Kotlin developers in India?
Check idiomatic Kotlin and Android judgment, not just years on a CV. Good candidates explain structured concurrency and cancellation, choose between StateFlow and SharedFlow with reasons, hoist Compose state correctly, and know how process death affects a ViewModel. Ask to see a module they wrote and its tests. Krapton shares work samples and lets you run your own technical round before anyone joins.
What team shape works for Kotlin Multiplatform work from India?
A shape with clear ownership of the shared module works best. Android engineers build features in Compose, one engineer owns the Kotlin Multiplatform module and its published API, and QA covers both platforms. If your iOS team stays in-house, they consume the shared framework while our lead joins their reviews for any API change, so the Swift side never receives surprises.
Who owns the app, keys and store listing when an India team builds it?
You own all of them. The Play Console account, Firebase projects, signing configuration and repositories are created under your organization, and the contract assigns the Kotlin source, build scripts and assets to you. Engineers sign NDAs and receive role-based access that you can remove at any time, which also makes ending or transferring the engagement straightforward.
How is a Kotlin codebase handed over to our in-house team?
It is handed over through documents, recordings and paired work. Your developers receive the module map, Gradle convention plugin notes, release and signing runbooks, and a list of known risks such as libraries due for upgrade. They then ship real tickets with an India engineer pairing, and the lead stays reachable through an agreed transition period for questions about the code.
