Java modernization services in Chicago
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.
US companies most often hire us for AI agents, HIPAA-ready healthcare software and SaaS MVPs for funded startups.

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 Chicago
Time-zone overlap
We overlap with Central Time mornings and offer flexible shifts for live stand-ups, with daily written updates in between.
HIPAA and US state privacy laws
For healthcare we build to HIPAA requirements: role-based access, encryption, audit logs and HIPAA-eligible cloud hosting, with BAAs in place for vendors that touch PHI. For other products we follow US privacy laws such as CCPA, and we sign NDAs before any work starts.
Billing
Invoices in US dollars (USD). Typical senior rates are $25 to $49 (USD) per hour, or a fixed price for a defined scope.
Where we help Chicago businesses most
Chicago's logistics, manufacturing and financial services companies come to us for software that connects to the systems they already run: TMS and ERP integrations, document automation, dashboards and AI assistants for operations teams.
SaaS and enterprise software
Fierce competition rewards fast product iteration and AI features. From internal tools to customer platforms, built and supported by one team.
Healthcare
Providers need HIPAA-aware portals, scheduling and claims automation. We build the platforms, integrations and internal tools this sector relies on.
Financial services
Banks and fintechs modernise onboarding, fraud checks and payments. Custom software that fits how these teams already work.
Retail and e-commerce
Direct-to-consumer brands live on conversion-focused stores and paid ads. From internal tools to customer platforms, built and supported by one team.

AWS US East (N. Virginia), Google Cloud us-east4 and Azure East US, 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.
