Java modernization services in South Africa
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.
South African companies most often hire us for fintech, healthcare software and AI automation.

Cost-effective delivery
Senior engineers at offshore rates with full code ownership.
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 South Africa
Time-zone overlap
South Africa is three and a half hours behind India, so our working days overlap for most of your morning and early afternoon.
The Protection of Personal Information Act (POPIA)
We design to POPIA's conditions for lawful processing: purpose limits, security safeguards and data-subject access, with data hosted in South African cloud regions when required. We sign NDAs before work starts.
Billing
Invoices in South African rand (ZAR) or US dollars. Typical senior rates are $25 to $49 (USD) per hour, or a fixed price for a defined scope.
Industries we work with in South Africa
South African companies use us for fintech, healthcare software and AI automation, designed to POPIA, with a strong daily overlap in working hours.
Mining
Mines invest in safety, monitoring and automation systems. We build the platforms, integrations and internal tools this sector relies on.
Financial services
Banks and insurers lead in mobile and digital channels. Custom software that fits how these teams already work.
Retail
National chains expand e-commerce and loyalty programmes. From internal tools to customer platforms, built and supported by one team.
Tourism and wine
Operators and estates sell to international visitors online. We build the platforms, integrations and internal tools this sector relies on.

Data hosting
AWS Africa (Cape Town), Google Cloud africa-south1 (Johannesburg) and Azure South Africa North, 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.
