Java modernization services in Jerusalem
Senior engineers who move at startup speed, plug into your codebase and work most of your day.
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.
Israeli startups and tech companies most often hire us for AI and LLM products, SaaS platforms and extra senior engineering capacity alongside their own team.

Speed, depth and direct communication
Israeli teams move fast and expect engineers who can keep up: senior, hands-on and direct. We work as an extension of your team, not an agency layer.
Senior engineers only
People who have shipped this before and can pick up an existing codebase in days.
Your processes, your tools
Your Git flow, your sprint rhythm, your Slack, including Sunday-to-Thursday schedules when agreed.
Straight answers
Direct feedback on scope, risks and trade-offs, so decisions happen quickly.
AI and deep tech
LLM apps, agents, RAG and computer vision built for production, not demos.
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 Jerusalem
Time-zone overlap
Israel is only two and a half to three and a half hours behind India, so our working days overlap for most of the day, including Sunday-to-Thursday schedules when agreed.
The Israeli Protection of Privacy Law and Data Security Regulations
We design products to the Protection of Privacy Law and the Privacy Protection (Data Security) Regulations: access controls, encryption, logging and data kept in the cloud region you choose. We sign NDAs and data agreements before work starts.
Billing
Invoices in Israeli new shekels (ILS) or US dollars. Typical senior rates are $25 to $49 (USD) per hour, or a fixed price for a defined scope.
Where we help Jerusalem businesses most
Jerusalem's healthtech, edtech and deep-tech companies work with us on web and mobile products, AI features and the platforms that support them.
Cybersecurity
Security startups need polished SaaS dashboards and fast releases. From internal tools to customer platforms, built and supported by one team.
Fintech
Payments and insurtech firms build global-first products. We build the platforms, integrations and internal tools this sector relies on.
Healthtech
Digital health firms combine medical data with AI. Custom software that fits how these teams already work.
Agritech and water tech
Irrigation and water innovators sell IoT platforms abroad. From internal tools to customer platforms, built and supported by one team.

AWS Israel (Tel Aviv) and Google Cloud me-west1 (Tel Aviv), 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.
