Java modernization services in Kenya
Mobile-first, low-bandwidth products with mobile money built in, from a senior team on overlapping 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.
Kenyan companies most often hire us for fintech and mobile-money apps, healthcare and AI.

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 Kenya
Time-zone overlap
Kenya is two and a half hours behind India, so our working days overlap for most of the day.
Kenya's Data Protection Act 2019
We design to Kenya's Data Protection Act: lawful processing, consent, security controls and data-subject rights, and we sign NDAs before work starts.
Billing
Invoices in Kenyan shillings (KES) or US dollars. Typical senior rates are $25 to $49 (USD) per hour, or a fixed price for a defined scope.
Where we help Kenya businesses most
Kenyan startups and businesses use us for fintech and mobile-money integrations, healthcare software and AI, designed to the Data Protection Act.
Mobile money and fintech
M-Pesa made mobile payments the default for most customers. From internal tools to customer platforms, built and supported by one team.
Agriculture
Tea, coffee and flower exporters adopt agtech and traceability. We build the platforms, integrations and internal tools this sector relies on.
Logistics
Mombasa port serves East Africa through tracking platforms. 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.
