Debug Microservices in NodeJS Application

I've got a NodeJS based backend microservices application in a mono repository. The CI/CD has already been set up using GitLab CI/CD, but some services are not properly configured due to some bugs. I need an experienced devops engineer to resolve the issues with the developer.

Ideal Skills:
- Proficient in NodeJS and microservices architecture
- Strong knowledge of GitLab CI/CD
- Experienced in debugging and troubleshooting complex backend systems.

Hours required: 4-8 hours
