Vasilis works on your project following the steps below.
Revisions may occur after the delivery date.
Diagnose the Issue
I review your code, logs, and reproduction steps to identify the exact root cause. I might isolate the failing component (API, startup, DB, config) and confirm the problem before applying any changes.
Implement the Fix
I apply a clean, tested fix to resolve the error and restore functionality. This includes code adjustments, configuration fixes, automated tests, and verifying the solution locally or in your environment.
