About this gig
Staring at a brutal Java stack trace, a broken Hibernate mapping, or a Spring Security configuration error for hours? Let me save your time and sanity.
As a dedicated backend developer specializing in the Java and Spring Boot ecosystem, I will jump into your codebase, run diagnostics, and systematically squash your backend bugs so your application runs flawlessly.
What I Can Fix For You:
- Spring Boot Core: Dependency injection issues, application configuration errors (application.properties/yml), and Beans initialization failures.
- REST APIs & Controllers: Routing issues, incorrect HTTP response status codes, JSON parsing/serialization errors, and broken endpoints.
- Database & Data Layer: Spring Data JPA errors, Hibernate mapping issues, lazy initialization exceptions, and connection pooling issues (MySQL, PostgreSQL, H2).
- Spring Security: Authentication/Authorization bugs, JWT implementation errors, and CORS policy blocks.
- Build Tools: Broken Maven pom.xml or Gradle build configurations and dependency version conflicts.

FAQ
Do I need to send you my entire project source code?
To fix the bug quickly, it is best to share the relevant code files (Controllers, Services, or configuration files) along with your full error stack trace. If the project is large, you can just share a minimized, reproducible example or the specific module where the error occurs.
What databases do you support for JPA and Hibernate issues?
I can debug data layer issues across all major databases commonly paired with Spring Boot, including MySQL, PostgreSQL, Oracle, H2, and MongoDB.
What happens if the bug cannot be fixed?
If I analyze your codebase and realize the issue cannot be resolved or falls completely outside my technical scope, I will inform you immediately and cancel the order so you receive a full refund. You only pay for a successful fix.
Can you help me debug a university or college Java assignment?
Yes! If you are a computer science student stuck on an assignment, I can help you find the logical errors, fix your Object-Oriented programming structures, and explain the code comments so you actually understand what went wrong.
Can you also help me teach the particular assessment?
Yes , i will do my best so you donot just get the service but actually can understand what thing actually went wrong and what could i have done better. Dosent matter if you are a total beginner you can ask any question or thing you donot understand about the code right away.
