Java

Java remains a workhorse for mission-critical systems, and CleverHub has the depth to use it well. We design clean domain models, enforce clear service boundaries, and apply proven patterns for resilience, concurrency, and data consistency.

• Frameworks: Spring Boot, Spring Cloud, JPA/Hibernate, JSP/Servlet, and JSF
• Architecture: REST and gRPC APIs, microservices, and event-driven design with Kafka
• Workflow and BPM: BPMN2 and JBoss jBPM
• Build and runtime: Maven/Gradle, JUnit, and tuned JVM deployments

• Scalable microservice back ends with circuit breakers and graceful degradation
• High-throughput networking and message-processing services
• Relational and NoSQL data layers with careful transaction design
• Performance tuning, GC analysis, and load testing

We treat operability as a first-class requirement: health checks, metrics, distributed tracing, and automated tests come standard, so your services are ready for production from the first deployment.
