Java modernization services in Toronto
Ship faster with senior engineers at offshore rates, overlapping your morning with a daily live stand-up.
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.
Canadian companies most often hire us for clinic and healthcare automation, AI agents and custom web and mobile apps.

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 Toronto teams
Time-zone overlap
We overlap with Eastern Time mornings and run flexible shifts for a live daily stand-up, with progress ready each morning.
PIPEDA and provincial privacy laws
We build to PIPEDA principles (consent, limited collection, safeguards and access), keep data in Canadian cloud regions when required, and sign NDAs and data agreements before work starts.
Billing
Invoices in Canadian dollars (CAD) or US dollars. Typical senior rates are $25 to $49 (USD) per hour, or a fixed price for a defined scope.
Built for Toronto's key sectors
Toronto-area clinics, startups and growing companies use us to build healthcare software, AI assistants and SaaS products, designed with PIPEDA in mind and with data kept in Canadian cloud regions when required.
Natural resources and energy
Mining and oil firms digitise field operations and reporting. Custom software that fits how these teams already work.
Financial services
Major banks and fintechs modernise digital banking. From internal tools to customer platforms, built and supported by one team.
AI research and tech
Strong AI ecosystem fuels startups shipping ML products. We build the platforms, integrations and internal tools this sector relies on.
Agriculture and food
Farm and food producers adopt supply-chain and traceability tools. 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.
