I will fix a java spring boot bug and add regression tests
Johjen
About this gig
Have a reproducible issue in your Java or Spring Boot application? I will investigate the agreed problem and deliver the work included in your package.
I work with Java backend applications, REST APIs, business logic, database access and batch processing.
BASIC: Diagnosis and a written root-cause report only; no code fix.
STANDARD: One pre-agreed small bug fix, a regression test, test results and handover notes.
PREMIUM: One pre-agreed bug fix plus agreed edge-case tests for the affected component.
Each package includes one revision within the original scope. Please message me on Fiverr before ordering to confirm project setup, scope and acceptance criteria.
AI-assisted tools are used only as agreed, with my own code review and validation. Share only authorised code with secrets and personal or production data removed.
Application development and new features are available through separately scoped custom offers. Full applications, major migrations, production deployment and ongoing support are not included in these packages.

I am an experienced Java and Spring Boot developer building backend applications, REST APIs and microservices. I help clients diagnose bugs, implement focused fixes, add regression tests and develop applications with clearly agreed requirements. My work covers business logic, database integration and batch processing. I use Codex and other AI-assisted tools with client permission, backed by my own code review and testing. Expect clear communication, maintainable code and practical handover notes. Message me to discuss scope, timeline and the right solution for your project.
FAQ
Does the Basic package include a bug fix?
No. Basic covers investigation of one reproducible issue and a written diagnosis only. Standard and Premium include a pre-agreed fix. Please message me before ordering so we can confirm scope and a runnable setup.
Can you develop a complete application or add features?
Yes. Application development, new features and larger changes require a separate custom offer with agreed requirements, deliverables, timeline and price. They are not included in these bug-fixing packages.
Do you use AI tools during development?
I use AI-assisted tools only as agreed with you, and review and validate the output myself. Tell me about any restrictions before ordering. Do not share secrets, personal data or production data; client code will not be sent to an AI service without permission.
What do you need to start?
A runnable project or minimal reproduction, setup steps, Java and Spring Boot versions, expected versus actual behaviour, and redacted error logs. Share only code you are authorised to provide. Production access and credentials are not required.
What is included in testing and revisions?
Standard includes a regression test for the agreed bug. Premium adds agreed edge-case tests for the affected component. One revision addresses the original scope, not new features or unrelated issues. Test environment limitations will be explained.
