I will modernize your legacy java web application
Victor Herrera
About this gig
Is your Java web application still running on JSP, Struts, Hibernate, or other legacy technologies? I will help you modernize it safely without disrupting your business.
I can assess the current codebase, identify technical debt, refactor legacy modules, improve maintainability, update integrations, and guide a practical modernization path. Depending on your package, you will receive an assessment and roadmap, targeted module modernization, or a broader modernization sprint with source code and detailed comments.
What I can help with:
- Legacy Java/JSP application assessment
- Struts and Hibernate modernization
- Refactoring and cleanup
- Compatibility and integration fixes
- Performance, security, and maintainability improvements
- Migration planning and technical guidance
Please contact me before ordering so we can review your application, scope, and goals. This Gig is for modernization and development work, not a complete rewrite of an entire enterprise platform in a single package.

FAQ
Can you work with old Java, JSP, Struts, or Hibernate applications?
Yes. I can assess and modernize legacy Java applications built with JSP, Struts, Hibernate, and related technologies. Please share the stack and current challenge before ordering.
Do you rewrite the entire application?
Not by default. I focus on safe, incremental modernization of agreed modules or components. A complete rewrite can be discussed separately after a technical assessment.
What do you need before starting?
Please provide a brief overview of the application, technologies, target module, current issue, access to relevant code or a repository excerpt, and any logs or reproduction steps.
Can you improve performance or security?
Yes. I can review bottlenecks and common security risks within the agreed scope and recommend or implement targeted improvements. A full audit requires a separate scope.
Will you include source code and comments?
Source code is included according to the selected package. Detailed code comments are included in Standard and Premium as listed in the package comparison.
