Build enterprise-grade backends, microservices, and cloud-native applications with our senior Java engineers. Spring Boot, Spring Cloud, and Jakarta EE expertise — delivering battle-tested, scalable systems from our nearshore offices.
Java remains the backbone of enterprise computing, powering 35% of backend systems globally. From banking to logistics, Java's stability, performance, and ecosystem make it irreplaceable. CALL IT DEV provides battle-tested Java architects and engineers who build systems that run for decades.
Why Enterprises Outsource Java Development to CALL IT DEV
Microservices Migration. Decomposing Java monoliths into microservices requires deep architectural expertise. We use Spring Cloud, service mesh, and event-driven patterns for safe migrations.
Performance Tuning. JVM tuning, garbage collection optimization, and connection pool management can dramatically improve throughput. Our engineers optimize JVM performance for production workloads.
Cloud-Native Adoption. Moving Java applications to Kubernetes requires containerization, config management, and observability. We implement cloud-native patterns with Spring Boot and GraalVM.
Legacy Modernization. Java EE/J2EE applications need modernization. We migrate from WebSphere/JBoss to Spring Boot with incremental strategies that minimize risk.
What we deliver
Spring Boot Microservices. Production-grade microservices with Spring Boot, Spring Cloud, and Spring Security. Service discovery, circuit breakers, and distributed configuration.
Enterprise Backend Systems. Jakarta EE and Spring-based backends for banking, insurance, and government. JPA/Hibernate, transaction management, and batch processing.
API Gateway & Integration. Spring Cloud Gateway, Apache Camel integration, and message-driven architectures with Kafka and RabbitMQ.
Cloud-Native Java. Containerized Java applications with Docker, Kubernetes, and Helm. GraalVM native images for serverless deployments.
Data Processing. Batch processing with Spring Batch, stream processing with Kafka Streams, and big data integration with Apache Spark.
Java Modernization. Java 8 to Java 21 upgrades, J2EE to Spring Boot migrations, and monolith-to-microservice decomposition.
Frequently asked questions
What Java versions and frameworks does CALL IT DEV use?
CALL IT DEV works with Java 17 and Java 21 (LTS releases). Our primary framework is Spring Boot 3.x with Spring Cloud for microservices. We also have expertise in Jakarta EE, Quarkus, and Micronaut for specific use cases.
Can CALL IT DEV migrate our Java monolith to microservices?
CALL IT DEV has completed 30+ monolith-to-microservice migrations. Our approach uses the Strangler Fig pattern, gradually extracting bounded contexts into independent services while maintaining the monolith. Typical migrations take 6-12 months with zero downtime.
How does Java development outsourcing pricing work?
CALL IT DEV Java development rates range from €40-60/hour for senior engineers. Dedicated teams with a tech lead start at €7,000/month per engineer. We offer fixed-price and time-and-materials models depending on project clarity.
Do you provide 24/7 support for Java applications?
CALL IT DEV offers 24/7 production support for Java applications with SLAs covering P1 (15-min response), P2 (1-hour response), and P3 (4-hour response) incidents. Our operations team in Casablanca provides continuous monitoring and incident response.
Can you optimize our Java application performance?
CALL IT DEV performance engineers specialize in JVM tuning (GC algorithms, heap sizing), database query optimization, connection pool management, caching strategies (Redis/Hazelcast), and profiling with tools like JProfiler, VisualVM, and Datadog APM.
How do I get started?
Use our instant order wizard at /order to scope service, team size and contact details — you get a quote in under 2 minutes, no credit card required. Or book a 15-minute discovery call.
How is pricing calculated?
We price per developer per hour or per fixed scope. Nearshore rates start at €25-€40/hour fully loaded; team seniority mix, engagement size and contract length affect the final rate.
