Why MetaDesign

Kotlin development consulting by top Kotlin development services.

Hire Kotlin development agency experts for Kotlin backend services. Hire Kotlin developers for Kotlin development consulting.

01

Null Safety

Kotlin eliminates NullPointerExceptions at compile time — the #1 cause of runtime crashes in Java applications.

02

Coroutines

Structured concurrency with coroutines — write async code that reads like synchronous code, with automatic cancellation and error propagation.

03

Concise Syntax

Data classes, sealed classes, extension functions, and destructuring — 40% less code than equivalent Java with better readability.

NULL-SAFE.
COMPILE.
SCALE.
SHIP.

Backend APIs

Spring Boot + Kotlin for enterprise APIs with coroutines, type-safe builders, and concise domain models.

Android

Native Android development with Jetpack Compose, Kotlin coroutines, and modern architecture components.

Multiplatform

Share business logic between Android, iOS, web, and backend with Kotlin Multiplatform.

Migration

Incremental Java-to-Kotlin migration — file by file, with 100% interoperability.

Our approach

Five stages,
paired end-to-end.

Predictable delivery. No black-box sprints.

01

Evaluate

Assess Kotlin fit and plan migration strategy from existing Java codebase.

02

Design

Domain models with data classes, sealed hierarchies, and coroutine patterns.

03

Build

Kotlin-idiomatic development with kotest, MockK, and detekt linting.

04

Test

Property-based testing, coroutine testing, and integration test suites.

05

Deploy

Standard JVM deployment — same infrastructure as Java, zero migration.

Customer value

Six places it pays back in the first sprint.

Real outcomes our clients report within the first engagement cycle.

Faster time-to-market

Production-ready teams that ship from week one — no ramp-up lag.

Reduced technical risk

Architecture reviews, code audits, and security scans baked into every sprint.

Measurable velocity

Cycle time, PR throughput, and defect density tracked from day one.

Cost predictability

Fixed-price or capped T&M — no surprise invoices, ever.

Continuous improvement

Retros, post-mortems, and process refinement every sprint.

Knowledge transfer

Your team grows. Documentation, pair programming, and workshops included.

Three ways to work
with our Kotlin team.

Scale up, scale down — zero procurement headaches.

Fixed-scope project

Start-to-finish delivery with total cost, timeline, and scope agreed upfront. Best for well-defined builds and launches.

BEST FORNew product launches

Dedicated team

A ring-fenced squad — PM, tech lead, engineers, QA — fully managed by us, embedded in your workflow.

BEST FORLong-running platforms

Staff augmentation

Plug senior engineers into your existing team and tools. You manage priorities, we deliver results.

FAQ

Asked first,
every time.

Don't see yours here? Send us the question — a principal engineer will reply within 24 hours.

Kotlin for teams that want null safety, coroutines, and concise syntax. Java 21 for teams with deep Java expertise and existing tooling. Both produce identical JVM bytecode.

Yes. Kotlin is 100% Java-interoperable. Convert files one at a time using IntelliJ's auto-converter, then refine to idiomatic Kotlin. Zero risk.

Yes. KMP is stable for sharing business logic between Android, iOS, and backend. Companies like Netflix, VMware, and Cash App use KMP in production.

Coroutines offer structured concurrency with built-in cancellation and error handling. Java virtual threads are simpler but less structured. Both solve the async problem — coroutines are more expressive.
