I will fix bugs and errors in your application or website
Walid El
About this gig
App throwing errors? Endpoint returning 500s? Something that worked yesterday suddenly broken? I'll find the root cause and fix it not just patch the symptom.
I debug Java and Spring Boot applications daily and can quickly diagnose:
- Runtime exceptions and stack traces (NullPointer and friends)
- Spring Boot startup and configuration failures
- Broken or misbehaving REST endpoints
- Spring Data / JPA / Hibernate and database query issues
- Authentication, CORS, and security misconfigurations
- Dependency, build, and Maven/Gradle problems
How it works: send me the error, your repo (or the relevant files), and steps to reproduce. I'll pin down the cause, fix it, explain what went wrong in plain language, and verify it works.
Fast turnaround most single bugs are resolved same or next day.
Not sure how big the problem is? Message me with the error message or a screenshot first and I'll tell you honestly which package fits before you order.
