Hire Kotlin Developers
Kotlin engineers for Android apps and shared KMP modules — idiomatic code, not Java with a new coat of paint.
Overview
What you get.
Kotlin is the default for serious Android work. Our developers write coroutine-safe, testable code — and know when Kotlin Multiplatform makes sense for shared logic with iOS.
From migrating Java legacy to greenfield Compose apps, we match engineers who have shipped on the Play Store and handled the device matrix your users actually use.
Skills
What our kotlin developers deliver.
Idiomatic Kotlin
Extension functions, flows, and sealed classes used with purpose.
Jetpack Compose
Declarative UI with state hoisting and navigation graphs.
Architecture
MVVM, clean architecture, and modularisation for large apps.
KMP optional
Shared business logic across Android and iOS when it saves real time.
Play Store
Release tracks, signing, and staged rollouts without surprises.
Quality
Unit tests, UI tests, and crash-free session targets.

Onboarding
From intro call to first sprint.
Discovery call
We learn your stack, sprint rhythm, timezone overlap, and the skills you need on day one.
Developer match
We shortlist engineers with relevant production work. You interview them before anyone starts.
Trial sprint
A short paid sprint to validate fit, communication, and velocity before a longer engagement.
Scale up
Add hours, developers, or QA as your roadmap grows — same team, no re-onboarding.
How quickly can a developer start?
Most roles can be matched within one to two weeks. We start with a discovery call, shortlist engineers for your review, and begin a trial sprint once you approve.
What timezone do your developers work in?
Our team is based in India with overlap for US and UK business hours. We align standups and overlap windows to your schedule during onboarding.
Can I interview developers before hiring?
Yes. You meet every developer we propose — technical interview, culture fit, or both — before they join your project.
What if the developer is not the right fit?
We replace or rotate within the engagement terms. The trial sprint exists specifically to catch mismatches early.
Do hired developers work exclusively on my project?
On dedicated engagements, yes — your developer is not shared across other client work during your contracted hours.
Can you sign an NDA and MSAs?
Yes. We routinely sign NDAs, MSAs, and security addenda before developers access your codebase.
