Java Development
for Australian businesses.

Large-scale business applications: ERP modules, supply chain systems, financial platforms, and operational tools. Spring Boot powering the backend, PostgreSQL or Oracle for the database, and a React or Angular frontend. Enterprise-grade architecture for enterprise-grade requirements.

Java excels at this scale. Dependency injection, transaction management, connection pooling, batch processing, and scheduled jobs. The Spring ecosystem handles every enterprise concern. The patterns are well-established and battle-tested across thousands of deployments.

We build new enterprise Java applications and extend existing ones. Additional modules, new integrations, API layers for mobile access, and reporting dashboards bolted onto the existing Java backend.

REST and GraphQL APIs built with Spring Boot. Authentication via OAuth2 or JWT, rate limiting, input validation, and auto-generated OpenAPI documentation. Java APIs that serve mobile apps, React frontends, and partner integrations.

Spring Boot makes Java API development productive. Embedded Tomcat, auto-configuration, Spring Data for database access, and Spring Security for authentication. A production-ready API without the XML configuration burden of older Java.

Integration APIs that connect Java systems to Xero, Salesforce, SAP, and internal platforms. Message-driven architecture with RabbitMQ or Kafka for systems that need event-based communication rather than synchronous API calls.

Your business runs on a Java application built ten or fifteen years ago. Java 8, maybe older. Spring MVC with XML configuration. JSP pages. EJB. The original team has moved on. But the system works, and the business depends on it.

We take over Java applications other teams built. Code audit, dependency review, security assessment, then a plan: upgrade in place, refactor module by module, or rebuild on Spring Boot. The approach depends on the code quality and business constraints.

Most enterprise Java applications can be modernised without a full rebuild. Java 8 to 21. Spring MVC to Spring Boot. JSP to a decoupled React frontend. XML configuration to annotations. The application keeps running throughout.

Spring Boot microservices for businesses that have outgrown their monolith, or are building new systems that need independent scaling and deployment. Each service handles one domain: authentication, billing, notifications, inventory.

Spring Cloud for service discovery, configuration management, circuit breakers, and API gateway. Docker containers deployed on AWS ECS or Kubernetes. Proper health checks, logging, and monitoring across services.

We are pragmatic about microservices. Most businesses do not need them. A well-structured Spring Boot monolith handles significant scale. Microservices add operational complexity. We recommend them only when the organisational and scaling benefits justify the cost.

Spring Batch for processing large data volumes: nightly imports, report generation, data reconciliation, bulk email sending, and file processing. Java handles these workloads reliably at scale.

Scheduled tasks with proper error handling, retry logic, and monitoring. Not cron jobs running scripts. Production-grade batch processing with transaction management, skip/retry policies, and job history tracking.

Common in finance, insurance, and logistics. Nightly bank statement imports, weekly invoice generation, daily inventory reconciliation. The kind of background processing that keeps Australian businesses running overnight.
