I will diagnose one java or spring boot API error
Huynh H
About this gig
Not sure why your Java API fails? Get the ROOT CAUSE in a WRITTEN REPORT.
I investigate one clearly described issue in a compatible Java or Spring Boot project. For $10, I spend up to one hour, including setup and reproduction attempts. Diagnosis only: code changes are not included.
WHAT YOU RECEIVE:
- A written report with findings and evidence where available
- Recommended next steps to resolve the issue
- One clarification round on the report
If the cause cannot be confirmed within the time limit, I explain what was checked, what remains uncertain and what is needed next.
WHAT HELPS ME:
- The expected behavior and the actual error
- Java/Spring Boot versions
- Sanitized logs or code, without secrets or production data
NOT SURE IT FITS? Message me before ordering and I will say clearly whether I can help.
SCOPE: code changes, new features, deployment, security audits and production access are excluded. A fix is a separate scope agreed through Fiverr.

FAQ
Does this guarantee a fix?
No. It covers up to one hour of investigation and a findings report. If the cause cannot be confirmed, I explain the checks, uncertainty and next steps.
What counts as one issue?
One symptom, such as one failing API request or one exception. Multiple unrelated errors require separate scope.
Does setup count toward the hour?
Yes. Local setup and reproduction attempts are included in the one-hour limit. Please contact me before ordering so we can check compatibility.
Are code changes included?
No. If a code fix is needed, I can assess it and propose a separate scope through Fiverr.
What does the revision cover?
One clarification round about the delivered report. New errors, further investigation and changed requirements are outside that round.
Do you access production?
No. Please provide sanitized logs and a minimal local example. Do not share passwords, tokens, private keys or customer data.
