FAQ
What information do you need to fix my bug?
A description of the issue, the relevant code or error logs, and your Spring Boot / Java version. A GitHub link or a zip of the relevant files works perfectly.
Can you fix bugs in an existing large codebase?
Yes. Share the relevant classes or modules — I don't need the entire project, just the code related to the issue.
What if the same bug reappears after delivery?
I provide free support for any issue directly related to the delivered fix. If the same bug comes back due to my fix, I will resolve it at no extra cost.
Do you fix bugs in plain Java projects (non-Spring)?
Yes. While I specialize in Spring Boot, I can debug plain Java applications, including issues with threading, collections, algorithms, and core Java libraries.
