Java modernization · Finland

Java modernization services in Finland

GDPR-first, fully documented and hosted in the EU, with a senior team working your morning hours.

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.

Finnish companies most often hire us for SaaS, gaming-adjacent apps and AI.

What matters to Finland teams

Privacy, quality and clear documentation

European teams tell us they want a partner who treats data protection and quality as the starting point, not an add-on. That is how we work.

01

GDPR by design

Data minimisation, consent, EU hosting and a signed data processing agreement before any personal data is touched.

02

Documentation you can audit

Written specifications, architecture notes, test reports and handover documents, so your team or auditors can follow every decision.

03

Accessible by default

Interfaces built to WCAG guidelines, helping you meet the European Accessibility Act for digital products and services.

04

Predictable contracts

Fixed scope and price, clear milestones and acceptance criteria, and full ownership of the code and IP.

What we do

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.

In depth

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.

Working with us from Finland

How we work with Finland clients

Time-zone overlap

Finland is two and a half to three and a half hours behind India, so our working days overlap for most of the day.

The GDPR and the Finnish Data Protection Act

We design to the GDPR and the Finnish Data Protection Act: data minimisation, consent, access controls, encryption, EU hosting and a data processing agreement signed before work starts.

Billing

Invoices in euros (EUR) or US dollars. Typical senior rates are $25 to $49 (USD) per hour, or a fixed price for a defined scope.

Data hosting

Google Cloud europe-north1 (Hamina), or AWS Europe (Stockholm), in your own cloud account, so data stays where your rules require.

Process

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.
