Java modernization services in Singapore
A senior team a short time-zone hop away, building products ready to scale across the region.
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.
Singapore companies most often hire us for fintech, logistics and AI products for Southeast Asia.

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.
Built for Singaporean teams
Time-zone overlap
Singapore is two and a half hours ahead of India, so our working days overlap for most of the day, with same-day calls and replies.
The Personal Data Protection Act (PDPA)
We design to the PDPA: consent, purpose limitation, protection and retention rules, with data hosted in Singapore cloud regions when required and NDAs signed before work starts.
Billing
Invoices in Singapore dollars (SGD) or US dollars. Typical senior rates are $25 to $49 (USD) per hour, or a fixed price for a defined scope.
Where we help Singapore businesses most
Singapore businesses use us to build fintech, logistics and AI products for the region, with English-speaking senior engineers, close time-zone overlap and data handled in line with the PDPA.
Finance and wealth
MAS-regulated firms build digital banking and wealth platforms. From internal tools to customer platforms, built and supported by one team.
Logistics and shipping
Port and transhipment hub needs tracking and optimisation. We build the platforms, integrations and internal tools this sector relies on.

Data hosting
AWS Asia Pacific (Singapore), Google Cloud asia-southeast1 and Azure Southeast Asia, in your own cloud account, so data stays where your rules require.
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.
