I will fix java spring boot bugs and backend errors
Vedad F
About this gig
I diagnose and fix problems in existing Java and Spring Boot applications.
I can help with REST API errors, exceptions, application startup failures, Spring configuration, JPA/Hibernate issues, PostgreSQL problems, authentication, Gradle builds, integrations, and incorrect backend logic.
I focus on reproducing the problem, finding the actual root cause, implementing the fix, and verifying the expected behavior.
This gig is for repairing an existing backend, not building an entire application from scratch.
If the issue affects multiple systems or you are unsure which package fits, message me with the error and reproduction details before ordering.

I’m a backend software engineer with over 8 years of professional experience building, debugging, and improving production software.
I specialize in solving problems in existing applications: backend bugs, broken APIs and integrations, deployment issues, database problems, build failures, and AI-generated code that doesn’t work as expected.
My tech stack: Java, Spring Boot, PostgreSQL, Docker, React, Scala, Spark, Gradle, microservices, and cloud infrastructure. I always focus on finding the root cause, fixing and verify the result.

FAQ
Do I need to know what is causing the bug?
No. Diagnosis is part of the service. You only need to show me what happens, what should happen instead, and how the issue can be reproduced.
What counts as one issue?
One issue is one clearly reproducible failure with one expected outcome. Unrelated bugs, new features, refactoring, or additional flows are separate scope.
Should I message you before ordering?
Yes if the root cause is unknown, the issue affects several components, or production infrastructure is involved. I can confirm the appropriate scope before you order.
