Java modernization services in Sydney
Practical, no-nonsense delivery from a senior team that overlaps your afternoon and works while you sleep.
Clarigo Infotech upgrades and modernizes Java applications: Java 8 or 11 to Java 17 or 21, older Spring and Spring Boot versions to current releases, javax to jakarta namespaces, and heavy application servers to lightweight containers. Where it helps, we split monoliths into services. Every step is covered by automated tests, so the application keeps working while it is upgraded.
Australian businesses most often hire us for AI automation, healthcare software and production-ready MVPs.

What our Java modernization covers
Java version upgrades
Java 8 or 11 to Java 17 or 21 LTS, including library and build-tool updates.
Spring Boot upgrades
Spring Framework and Spring Boot 1.x and 2.x to current versions, including the javax to jakarta move.
App server to containers
WebLogic, WebSphere, JBoss or Tomcat deployments moved to Docker, Kubernetes or managed cloud services.
Monolith to microservices
Carefully split large Java applications into services, only where it improves delivery or scale.
Build and CI/CD
Maven and Gradle cleanup, automated tests and pipelines that make every release safe.
Performance and security
Dependency and vulnerability fixes, JVM tuning and profiling for faster, safer applications.
How we approach Java modernization
Why move to Java 17 or 21
Newer long-term-support versions bring better performance, security updates and language features, and current Spring Boot versions require them. Staying on Java 8 means growing security and hiring risk.
Upgrade path, not a rewrite
We upgrade in stages (build tools, dependencies, language version, framework), testing at each stage, so you always have a working, releasable application.
Remote, but close to Sydney
Time-zone overlap
Indian mornings overlap with Sydney afternoons, so you get a daily stand-up in your working day and work handed over in the afternoon moves forward the same evening.
The Australian Privacy Act and Australian Privacy Principles
We build to the Australian Privacy Principles (open handling, security, access and correction), host data in Australian cloud regions when required, and sign NDAs and data agreements before work starts.
Billing
Invoices in Australian dollars (AUD) or US dollars. Typical senior rates are $25 to $49 (USD) per hour, or a fixed price for a defined scope.
Built for Sydney's key sectors
Sydney businesses work with us for AI automation, healthcare software and new products, built to the Australian Privacy Principles and hosted in Australian cloud regions when needed.
Mining and resources
Remote operations need asset tracking, safety and automation software. Custom software that fits how these teams already work.
Education
Universities serve international students through digital platforms. From internal tools to customer platforms, built and supported by one team.
Financial services
Open banking under the Consumer Data Right drives new apps. We build the platforms, integrations and internal tools this sector relies on.
Tourism
Operators depend on online bookings and destination marketing. Custom software that fits how these teams already work.

How it works
1. Free assessment
We review your code, dependencies, infrastructure and data, then give you a written migration plan, risks and a fixed quote.
2. Plan and safety net
We add automated tests and monitoring around what exists today, so every change can be checked against the old behaviour.
3. Migrate in small steps
Module by module, with both versions running side by side where needed. You see progress in a demo every week.
4. Cut over and support
A planned switch-over with a rollback path, then the same engineers stay on to fix, tune and keep it current.
