I will analyze your production logs and debug distributed systems
Jessica A
About this gig
I help you find the root cause of bugs and issues in distributed systems by analyzing production logs.
I have real experience resolving 5-10 production incidents per week in a complex environment with 70+ microservices, using Elasticsearch, Kibana, and OpenTelemetry to trace errors across distributed flows.
What I can help you with:
- Analyzing logs to find the root cause of an error
- Tracing requests across multiple microservices
- Debugging issues that involve more than one service
- Recommendations to improve your logging/observability setup
What I need from you:
- Access to your logs (Kibana, Elasticsearch, or raw log files)
- Description of the issue and when it started happening
- Architecture overview if the system has multiple services
Message me before ordering if you're not sure your case fits.

FAQ
Do you need full access to my system?
No, I just need access to your logs (Kibana, Elasticsearch, or raw files) and a description of the issue. I don't need full system access for most analyses.
What if the issue involves multiple microservices?
That's exactly what I specialize in — I have real experience tracing errors across distributed systems with 70+ microservices.
Can you fix the bug too, or just diagnose it?
My focus is diagnosis and root cause analysis. If you need the fix implemented as well, check out my "Bug Fixing" gig or message me to discuss.
