Native Android apps, Kotlin Multiplatform projects, and server-side Kotlin built by senior engineers who ship production mobile and backend systems.
Trusted by engineering teams at
Production Android applications built with Kotlin, Jetpack Compose, and modern Android architecture (MVVM, MVI). Material 3 design, adaptive layouts for phones, tablets, and foldables. Apps that follow Google's current best practices, not patterns from five years ago.
Share business logic across Android, iOS, web, and desktop without rewriting it per platform. KMP lets you write networking, data models, validation, and caching once in Kotlin, then use native UI on each platform. Google officially recommends KMP for cross-platform business logic as of 2024.
Backend services in Kotlin using Ktor or Spring Boot. Coroutines for efficient concurrent request handling without callback complexity. Kotlin's null safety and expressive syntax reduce production bugs compared to Java backends. Ideal when your Android team also owns backend services.
Migrate existing Android apps from Java to Kotlin incrementally. Kotlin is 100% interoperable with Java, so migration happens file by file without breaking the build. We prioritize high-change areas first to maximize the return on migration effort. Most apps complete migration in 8-16 weeks.
Kotlin declarative UI for Android that replaces XML layouts with composable Kotlin functions. Less boilerplate, better state management, built-in animation APIs, and Material 3 support. Compose is Google's recommended approach for all new Android UI and powers apps like Google Maps and Play Store.
Custom Android SDKs, payment integrations, and shared libraries for distribution via Maven Central or private repositories. Proper API design, backward compatibility, semantic versioning, and documentation. Built for other developers to consume without frustration.
Writing Java patterns in Kotlin syntax misses the point. We use Kotlin idioms: sealed classes for state modeling, coroutines for async work, extension functions for clean APIs, and data classes for immutable models. The code should feel like Kotlin, not Java wearing a Kotlin costume.
Jetpack Compose is not optional for new projects. XML layouts, Fragments, and the View system are legacy patterns. We build with Compose from day one: composable functions, unidirectional data flow, and declarative state management. The result is less code, fewer bugs, and faster development.
When using KMP, business logic lives in shared Kotlin modules. UI stays native to each platform. We resist the temptation to share UI across platforms because users notice when an app does not feel native. Shared logic, native UX.
Compose UI tests, integration tests with real dependencies, and screenshot tests for visual regression. We test user behavior, not implementation details. A test suite should give your team confidence to ship changes, not slow them down with false positives.
Every Kotlin project is built so your team can maintain it independently. Clean architecture, documented decisions, automated CI/CD, and zero proprietary tooling. We build for your engineers, not our retention.
Define screens, user flows, and technical approach. Choose between Jetpack Compose (Android-only) and KMP (multiplatform). If you have an existing Java Android app, we audit it and plan the migration path. Deliverable: technical spec, architecture diagram, and Figma wireframes.
Build a custom Compose component library implementing your brand's design language. Material 3 theming, dynamic color support, and adaptive layouts for different screen sizes. Components tested in isolation with Compose Preview and screenshot tests.
Sprint-based Kotlin development with internal builds distributed via Firebase App Distribution for real-device testing. Weekly demos. Kotlin's concise syntax and Compose's declarative model mean faster iteration than traditional Android development.
Testing across phones, tablets, and foldables. Compose UI tests, integration tests, and performance profiling with Android Studio's Layout Inspector and baseline profiles. Play Store submission with proper listing optimization.
Bug fixes, Android OS compatibility updates (Android 16 targeted), feature development, and Play Store policy compliance. Ongoing performance monitoring with Firebase Crashlytics and Performance Monitoring.
Full-time on your project, integrated into your team. Engineers proficient in Kotlin 2.1, Jetpack Compose, KMP, and modern Android architecture patterns.
Android + backend + QA for a complete mobile team. Architecture, implementation, testing, and Play Store deployment covered.
Fixed scope, milestone-based delivery. Defined specs, agreed milestones, and transparent pricing.
Talk directly with engineers, not sales. We will assess fit and give honest next steps.

Kotlin app development costs vary by complexity. Simple apps with standard UI run $15,000 to $40,000. Mid-complexity apps (e-commerce, social, data-heavy) range from $40,000 to $120,000. Enterprise Android apps with offline support, SSO, and compliance features run $120,000 to $300,000+. Dedicated Kotlin developer hiring starts at $3,500/month. KMP projects that share logic across iOS and Android typically cost 20-30% less than building separate native apps.
