FAQ
What information do you need to start?
I need access to your codebase, a description of the issue, error logs or screenshots, and steps to reproduce the bug. The more details you provide, the faster I can fix it.
Can you work with older Java versions?
Yes! I work with Java 8 through Java 21, including legacy Spring, Spring Boot 1.x/2.x/3.x, and older JavaEE projects.
What if you can't fix the issue?
If the issue is beyond the agreed scope or truly unfixable, I'll provide a full refund. I always communicate honestly about what's possible before you order.
Do you offer ongoing support after delivery?
Yes! I provide support after delivery to ensure the fix works properly. For long-term maintenance, message me to discuss a custom arrangement.
Can you fix issues in other Java frameworks?
Absolutely. Besides Spring Boot and Spring MVC, I also work with JavaFX, Hibernate, JSP/Servlets, plain Java applications, JavaFX and Java Swing applications.
