Sobre este Serviço
Stuck on a persistent Spring Boot error, failing REST API, or broken backend logic? Let me help you fix it quickly so you can get your application back on track.
I am a senior backend software engineer specializing in Java and Spring Boot ecosystems. Whether you're dealing with cryptic stack traces, broken authentication flows, or slow database queries, I will diagnose, debug, and fix your issues with clean, production-ready code.
What I Can Fix & Optimize For You:
Spring Boot Errors: Application failed to start, dependency injection, and configuration issues.
REST API Issues: Incorrect HTTP responses, payload mapping, CORS errors, or endpoint failures.
Spring Security & Auth: JWT authentication, OAuth2, RBAC, and permission bugs.
Database & Persistence: Hibernate/JPA issues, N+1 query problems, migration errors, and Liquibase/Flyway setup.
Performance & Refactoring: NullPointerExceptions, memory issues, clean code optimization, and unit testing.
How We Will Work Together:
1. Message Me First: Share the error stack trace, code snippet, or expected vs. actual behavior.
2. Fast Diagnosis: I will review the issue and confirm the right package or custom offer.
