I will fix java spring boot bugs and rest api errors
Mouad Rarhib
Acerca de este Servicio
Is your Spring Boot app failing to start, returning API errors, or behaving incorrectly?
I diagnose and fix Java Spring Boot bugs in existing projects, including REST controllers, request validation, JPA/Hibernate queries, database mappings and JWT/Spring Security access issues.
Choose a focused package:
BASIC: 1 agreed small bug.
STANDARD: up to 3 agreed REST API or database bugs.
PREMIUM: up to 5 agreed backend bugs, including JWT/Spring Security issues.
All packages include investigation, corrected source files, useful code comments, a summary of the cause and fix, and steps to verify the agreed behavior.
One bug means one reproducible issue with a defined expected result in one existing Spring Boot application. Send the error, logs, reproduction steps and setup instructions before ordering so I can confirm scope and compatibility.
New features, major refactoring, framework upgrades, migrations, infrastructure incidents and deployment require a custom quote. Revisions cover the agreed fixes. Gallery screenshots show APIs from my TenantHub portfolio project.

Backend engineer with a double Master's in Big Data/AI and Software Engineering. I ship production systems, not tutorials: a real-time vehicle tracking dashboard, a Slack-integrated HelpDesk, and JWT-secured task platforms built for real teams.
Stack: Java/Spring Boot, Node.js/Express, Laravel, React, Angular, PostgreSQL, Docker, Kubernetes, CI/CD, AWS. I also build fast MVPs with Supabase + React when speed matters.
New to Fiverr, not new to engineering. I reply fast, scope clearly, and deliver code I'd put my name on. Based in Casablanca — fluent in English, French, and Arabic.

FAQ
What counts as one bug?
One bug is one reproducible issue with a defined expected result in one existing Spring Boot app. Several symptoms can share a cause; I review your steps and logs before we agree on the number and scope of fixes.
Can you fix JPA, Hibernate and database errors?
Yes, I can investigate query, mapping, persistence and connection issues with Spring Data JPA/Hibernate and PostgreSQL or MySQL. Standard and Premium cover agreed database bugs. Migrations, data recovery and major schema changes need a custom quote.
Can you fix JWT and Spring Security problems?
Premium can include agreed bugs in an existing JWT or Spring Security setup, such as token validation or role access errors. Building a new login system, OAuth2 integration or performing a security audit requires a custom quote.
What will I receive after a fix?
You receive corrected source files, useful code comments, an explanation of the cause and changes, and steps to verify the fix locally. Deployment, hosting and infrastructure work require a custom quote.
What should I send before ordering?
Send the exact error, sanitized logs, reproduction steps, expected result, Java/Spring Boot versions and local setup instructions. Share relevant source files or repository access for review. Please message me first so I can confirm the issue fits the package.
What does a revision include?
A revision covers corrections to the agreed bug fixes and expected behavior. New bugs, features, changed requirements, upgrades and major refactoring require a separate quote. Please provide reproducible examples when reporting an issue.
