Java Development Company

Absolutely. Java 21 with virtual threads, pattern matching, and records is a modern language. Spring Boot 3.x offers fast startup and low memory with native compilation. Java remains the top choice for enterprise systems that need long-term support, hiring availability, and proven reliability at scale.

Yes. We migrate Java 8/11 apps to Java 21, upgrade Spring MVC to Spring Boot, decompose monoliths into microservices, and containerize for Kubernetes deployment. We do this incrementally to avoid rewrite risk, module by module with full regression testing.

Cost depends on the system you need. A single Spring Boot microservices backend is the more contained tier and scopes lower. Full enterprise systems that add multiple services, messaging, and monitoring carry more architecture and integration work, so they scope higher. While Java engineering rates run slightly higher than some stacks, the long-term maintenance cost is lower thanks to strong typing and mature tooling. We scope your exact figure on a free call before work starts.

We primarily use Kotlin for new Android apps, as Google recommends it as the preferred language. For existing Java Android codebases, we maintain and extend in Java or incrementally migrate to Kotlin. For cross-platform needs, we recommend Flutter instead.

JUnit 5 for unit tests, Mockito for mocking, Testcontainers for integration tests with real databases, and Gatling for load testing. We target 80%+ code coverage and run tests in CI before every merge. Contract testing with Pact for microservices communication.

We scope a dedicated Java team to the seniority you need and the size of the system. Spring Boot and microservices experience is part of that scope, not a separate line item. Each engineer is full-time at 160 hours a month, and we run the team as your build partner. Book a call and we will hand you the figure.

Java with Spring Boot is better for teams that need mature tooling, large talent pools, and extensive library ecosystems. Go is better for performance-critical services needing minimal memory footprint. Java's virtual threads in JDK 21 closed much of the concurrency gap. For most enterprise backends, Java offers lower total cost of ownership.

Yes. We have modernized 15+ legacy Java systems, taking them from Java 8 to 21, monolith to microservices, on-premise to cloud. Most of these run 3 to 6 months. The real variable is your codebase, how big it is and what shape it is in, and that is what sets the cost. We put a dedicated Java team on it, start with a scoping call, and can begin within days.
