Jelevaite

Many organizations today are managing core applications based on monolithic architectures and outdated Java versions.

This scenario generates several operational challenges:

• Widespread technological obsolescence
  Unsupported JDK versions, outdated libraries, and legacy frameworks that are difficult to maintain

• Difficulty in architectural evolution
  Complex monolithic systems that are difficult to transform into modular architectures or microservices

• High risks during refactoring
  Manual changes that are difficult to standardize and risk of regressions

• Long timelines and high costs
  Analysis and interventions that are often slow, with a direct impact on the ability to innovate

• Security and compliance issues
  Known vulnerabilities that are difficult to manage on obsolete stacks

The problem is not the technology itself, but the way its evolution is managed: manual approaches that are poorly structured and difficult to scale.

Jelevaite has been designed as a solution that supports the team throughout the entire modernization journey, without replacing developers but assisting them in the most complex phases.

The process starts with an automated analysis phase of the code and dependencies, which makes it possible to build a clear picture of the application’s current state. Based on this, the solution identifies the main gaps compared to the latest Java versions and highlights the areas that require intervention.

Refactoring activities are managed within a structured workflow integrated with the tools already in use, such as code repositories and CI/CD pipelines. The proposed changes are presented clearly and in context, allowing developers to evaluate, adapt, and approve them according to their needs, without interrupting the normal development cycle.

One of the most relevant aspects of the solution is the way it supports code interventions, making them precise and consistent with the application context. The changes follow updated standards and logic, without introducing discontinuities into the existing system. This makes it possible to manage both version upgrades and architectural evolution while maintaining stability and predictability throughout the entire process.

The solution also integrates a testing and validation pipeline that reuses existing tests and introduces additional checks to detect potential regressions. In this way, every step of the modernization process is supported by an appropriate level of control.

Finally, all activities are tracked and documented. Logs, reports, and change manifests always provide visibility into what has been done and why, facilitating both team operations and any audit or compliance requirements.

Jelevaite automates some of the most complex activities involved in Java application modernization:

Automated code analysis
Identification of technological gaps, outdated dependencies, and critical areas

Guided Java version upgrades
Support for adopting LTS versions and updating the application stack

Assisted refactoring
Changes proposed in a clear, contextualized, and developer-approvable way

Progressive architectural evolution
Support for transforming monoliths into modular systems or microservices

Automated testing and validation
Continuous verification to prevent regressions and ensure stability

Full traceability
Logs, reports, and change manifests for audit, compliance, and sharing

With JElevAIte, Java application modernization moves from a manual approach to an artificial intelligence-driven model.

Traditional approach

• Manual and often incomplete analysis

• Complex and non-standardized refactoring

• High risk of regressions

• Invasive interventions that are difficult to manage

• Dependency on experts

With Jelevaite

• Automated and complete code analysis

• Guided and controlled refactoring

• Gradual and non-invasive evolution

• Continuous testing and integrated validation

• Total control and transparency of changes
