I will develop or fix Java backend functionality

I will develop, fix or improve small Java backend functionalities in an existing application.

I can help with:

* Core Java development
* Bug fixing
* Object-oriented programming
* Business logic implementation
* Refactoring existing code
* Data processing
* Small backend features
* Troubleshooting existing Java code
* Improving code structure and maintainability

I have several years of professional experience in software development, mainly with backend applications, APIs and databases, and I am currently actively expanding my work with Java.

This service is best suited for small, well-defined Java tasks rather than large enterprise projects.

Before starting, I will review the requirements and provide an estimate of the expected effort whenever possible.
