What does a Kotlin
development company deliver?
See the types of projects NextAge delivers with a dedicated squad, fixed scope and guaranteed SLA. Understand when Kotlin is the most solid technical choice for your roadmap.
Back-end development
Kotlin combines conciseness, safety and interoperability with the Java ecosystem, making it a solid choice for modern, scalable back-end development. NextAge builds robust services, APIs and enterprise applications with architectures ready to evolve and grow.
Technologies: Kotlin, Spring Boot, Ktor, Spring Framework, Hibernate, JPA, PostgreSQL, MongoDB, Redis
API and microservices development
Kotlin makes it possible to build efficient APIs and microservices, with more concise code and integration with proven technologies from the Java ecosystem. NextAge builds and integrates services that connect systems, applications and platforms, with a focus on security, scalability and consistent delivery.
Technologies: Kotlin, Spring Boot, Ktor, REST, GraphQL, Swagger/OpenAPI, OAuth2, JWT, API Gateway
Android applications
Kotlin is the language officially recommended by Google for modern Android development. NextAge builds and evolves native apps with a focus on performance, maintainability, security and a consistent user experience.
Technologies: Kotlin, Android SDK, Jetpack, Jetpack Compose, Coroutines, Room, Retrofit
Cross-platform development
With Kotlin Multiplatform, part of the business logic can be shared across platforms, reducing code duplication without giving up native experiences. NextAge can structure cross-platform applications with an architecture ready for continuous evolution and maintenance.
Technologies: Kotlin Multiplatform, Compose Multiplatform, Kotlin Coroutines, Ktor, Android and iOS integration
Java application modernization
Interoperability between Kotlin and Java makes it possible to modernize existing applications gradually, without a complete rewrite of the system. NextAge uses Kotlin in incremental evolution strategies, refactoring critical components and introducing a more modern technology base while keeping risks and operational impact under control.
Technologies: Kotlin, Java, Spring Boot, Spring Framework, incremental migration, code refactoring, Docker and cloud
Integration with enterprise systems
Because it is interoperable with Java, Kotlin can be integrated with the applications, libraries and services already in place in enterprise environments. NextAge builds solutions that connect systems, APIs and data sources, keeping business flows integrated and ready to evolve.
Technologies: Kotlin, Spring Integration, Apache Kafka, REST, GraphQL, messaging, relational and NoSQL databases
… and whatever else it takes to turn your development capacity into predictable deliveries.
