I will fix bugs and errors and troubleshoot your java spring boot application

Hello! Are errors or unexpected behaviors plaguing your Spring Boot REST API integration? I specialize in debugging and fixing all kinds of Spring Boot application issues. Whether you're facing basic integration errors, authentication/authorization failures, or performance bottlenecks, I will resolve them and get your API running smoothly.

My services include:

• REST API & Integration Bugs: Identify and fix issues in RESTful endpoints and microservice . This covers JSON parsing errors, missing resources, CORS/config problems, and third-party API misconfigurations.

• Authentication & Security Fixes: Resolve login, JWT/Spring Security, OAuth, or roles/permissions errors. I fix Spring Security config mistakes and authentication failures.

• Database and JPA Errors: Debug JDBC/Hibernate issues like SQL exceptions, data mismatches, or mapping errors. I handle MySQL connectivity and JPA/Hibernate integration bugs.

• Performance Troubleshooting: Optimize slow endpoints and resolve memory leaks or threading issues. I can profile your app to find bottlenecks, tune queries, and improve throughput.
