Since 2010
15+ Years Building
Kotlin Development Across Mobile, Multiplatform, and Server
Kotlin done properly: coroutine-driven Android apps, Kotlin Multiplatform where sharing genuinely pays, and Ktor or Spring Boot services in the same language. Senior engineers, fixed written quotes, 100% source-code ownership.

What Kotlin Development Means at Moxace
Kotlin development at Moxace spans Android apps, Kotlin Multiplatform libraries, and backend services. We treat coroutines and structured concurrency as the foundation of everything we write, because in Kotlin, concurrency mistakes are architectural mistakes.
Bring us in for Android work that outgrew its first architecture, for KMP initiatives where one shared business-logic core could serve iOS and Android, or for JVM backend teams who want Kotlin's safety without abandoning the Spring ecosystem they already run.
What Every Kotlin Development Engagement Includes
Scoped in writing before the first sprint. If it is not on this list, we will tell you exactly what it costs to add it.
Coroutine-first architecture
Structured concurrency, Flow, and cancellation handled correctly across network, database, and UI layers, so nothing leaks or races.
Kotlin multiplatform
Shared business logic, networking, and persistence for iOS and Android, with native UIs where the platform expects them.
Android at scale
Modularized codebases, Compose design systems, and Gradle build hygiene for teams past the single-module stage.
Ktor and spring services
Kotlin backends on Ktor for lean services or Spring Boot where the JVM ecosystem is already in place.
Java interop pragmatism
Incremental adoption inside existing JVM codebases, mixing Kotlin and Java without a rewrite mandate.
Testability by design
Turbine-tested flows, fakes over mocks, and CI pipelines that run the full matrix on every merge.
What You Can Build With Kotlin Development
Representative outcomes our Kotlin Development teams deliver.
Android products
Consumer and enterprise Android apps built Compose-first with offline-first data layers.
KMP shared cores
One Kotlin core serving Android and iOS apps, cutting duplicated logic out of both teams' roadmaps.
Backend APIs
Kotlin services for payment processing, integrations, and internal platforms on the JVM.
SDKs and libraries
Kotlin libraries distributed to internal teams or customers, with semantic versioning and documentation.
How the engagement runs
From first call to handover, with a working build to see every two weeks.
- 01
Scoping call
One hour on product, codebase, and where Kotlin fits, ending with a fixed written quote.
✓ step 01 complete - 02
Architecture blueprint
Module boundaries, coroutine structure, and multiplatform split documented before the first line.
✓ step 02 complete - 03
Two-week build sprints
Working builds demoed every two weeks, with your feedback folded into the next sprint.
✓ step 03 complete - 04
Continuous QA
Unit, instrumentation, and multiplatform tests running in CI, plus device-matrix passes for release candidates.
✓ step 04 complete - 05
Handover
Documented modules, onboarding notes for your engineers, and full code and IP ownership transferred to you.
✓ step 05 complete
The adjacent stack we bring
Kotlin Development never ships alone. These are the pieces we routinely wire around it.
Coroutines and flow
The concurrency backbone for apps and services, with structured cancellation throughout.
Jetpack compose
Declarative Android UI with design tokens shared across products.
Kotlin multiplatform
Shared logic for iOS and Android via KMP, with native interfaces on each side.
Ktor
Lightweight Kotlin services for APIs, webhooks, and integrations.
Exposed and room
Typed persistence on the server and device, with migrations treated as production database work.
AI inside the build
Where models genuinely earn their place in Kotlin Development work. Each ships wired to your data and sharpens as usage compounds.
On-device ML on Android
ML Kit and TFLite integration for vision and text features running locally.

Every build ships with
Standard inclusions on every engagement. Nine things you never have to ask for.
100% source code, full IP
The complete unencrypted codebase transfers to you, with documentation and deployment scripts.
Named senior team
The engineers who scope your build are the ones who write it. No bait-and-switch staffing.
Architecture blueprint
A documented system design covering data model, integrations, and scaling path, written before the first sprint.
Sprint demos every 2 weeks
A working build demonstrated every two weeks, so you steer continuously instead of waiting for a reveal.
QA and security testing
Automated and manual QA on every build, plus a security checklist on each release candidate.
CI/CD and monitoring
Pipelines, cloud deployment, alerting, and observability configured from day one, so launch is a rehearsed event.
Fixed written pricing
A scoped quote in writing before work starts. No hourly meter, no surprise invoices mid-build.
60 days support
A post-launch support window covering bug fixes and environment issues, standard on every engagement.
Handover documentation
Code, infrastructure, and runbooks documented so any team, ours or yours, can pick the product up cleanly.
Hire a dedicated team or run a Fixed-scope project
Both tracks deliver the same Kotlin Development quality bar. The difference is control, timeline, and how the work is priced.
| Criteria | Dedicated Team (Hire) | Fixed-Scope Project |
|---|---|---|
| Best for | Ongoing Kotlin Development work with evolving priorities | A defined outcome with a clear finish line |
| Pricing | Predictable monthly team rate | Fixed written quote after scoping |
| Team | Engineers embedded in your rituals and tooling | Our PM, our process, demos every two weeks |
| Flexibility | Reprioritize the backlog any week | Change requests estimated and scheduled |
| Source code and IP | 100% ownership on delivery | 100% ownership on delivery |
| Start time | Team in place within 1-2 weeks | Kickoff within days of the signed scope |
