What we build with Kotlin

From Android apps to backend services.

Native Android apps

Modern Android apps built with Jetpack Compose, clean architecture and coroutines.

Spring Boot & Ktor APIs

Robust, type-safe backend services and REST/GraphQL APIs that scale under load.

Kotlin Multiplatform

Shared business logic across Android, iOS and backend with KMP and Compose Multiplatform.

Admin & internal tools

Server-rendered portals and data-dense back-office tools on the JVM stack.

Microservices & events

Coroutine-based microservices, message queues and event-driven pipelines.

AI-powered features

LLM integrations, smart search and on-device ML wired into your Kotlin app.

Why choose Kotlin Senior Kotlin talent
Why Kotlin

A safe, modern bet for the JVM and Android.

  • Null-safety by design

    The type system eliminates whole classes of null-pointer crashes before they ship.

  • Concise & concurrent

    Coroutines make async code readable, while less boilerplate keeps teams fast.

  • 100% Java interop

    Adopt Kotlin gradually inside an existing Java codebase with zero rewrites.

FAQ

Hiring Kotlin engineers, answered.

How fast can a Kotlin engineer start?

Individual hires onboard in 5–7 days; a dedicated Kotlin team is typically running within 2–4 weeks.

Do you build both Android and backend with Kotlin?

Yes, our engineers ship Jetpack Compose Android apps and Spring Boot or Ktor backends, often sharing logic via Kotlin Multiplatform.

Can you migrate our Java codebase to Kotlin?

Absolutely. Thanks to full Java interop we adopt Kotlin file-by-file, with no big-bang rewrite and zero downtime.

What seniority do you provide?

Senior-only, vetted engineers, every candidate passes technical and communication screening before reaching your team.
