Java Development Company
Enterprise-grade applications and microservices
We build Java applications for organizations that need reliability, scalability, and long-term maintainability. Our team has delivered 35+ Java projects — from Spring Boot microservices processing 100K+ transactions/hour to enterprise platforms serving 50K+ internal users. Java's mature ecosystem and strong typing make it the backbone of mission-critical systems. Need dedicated talent? Hire Java developers from our pre-vetted team. For end-to-end product delivery, explore our custom software development services.
What sets our java development apart
Spring Boot Microservices
We build and decompose monoliths into Spring Boot microservices with Spring Cloud, service mesh integration, and container orchestration. Production-tested patterns for distributed systems.
Enterprise Integration
Integration with SAP, Salesforce, Oracle, and legacy ERP systems. We build adapters, middleware, and event-driven architectures that connect your existing infrastructure.
High-Availability Architecture
Multi-region deployment, database replication, circuit breakers with Resilience4j, and automated failover. We design for 99.99% uptime SLAs.
JVM Performance Tuning
Garbage collector selection, heap sizing, thread pool optimization, and profiling with JFR and async-profiler. We eliminate memory leaks and reduce p99 latency.
Kotlin & Modern Java
We use Java 21 features (virtual threads, pattern matching, records) and Kotlin for Android and server-side projects. Modern language features with backward compatibility.

Common questions about java development
Is Java still relevant for new projects in 2026?
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.
Can you modernize our legacy Java application?
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.
How do Java development costs compare to other technologies?
Java enterprise applications typically cost $25,000-$80,000 for a Spring Boot microservices backend. Full enterprise systems with multiple services, messaging, and monitoring range from $60,000-$200,000. While individual Java developer rates are slightly higher, the long-term maintenance cost is lower due to strong typing and mature tooling.
Do you build Android apps with Java or Kotlin?
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.
What testing practices do you follow for Java projects?
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.
How much does it cost to hire a dedicated Java developer?
Dedicated Java developers cost $2,000-$3,000/month for junior, $3,000-$5,000/month for mid-level, and $5,000-$7,500/month for senior engineers. Spring Boot and microservices specialists are at the higher end. Full-time, 160 hours/month. Equivalent US Java developers cost $10,000-$16,000/month.
Java vs Go — which is better for enterprise microservices?
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.
Can you modernize our legacy Java enterprise system?
Yes. We have modernized 15+ legacy Java systems — migrating from Java 8 to 21, monolith to microservices, and on-premise to cloud. A typical modernization takes 3-6 months and costs $60,000-$200,000. Get a dedicated Java team from $5,000/month per developer to start the assessment within 1 week.
