GCP/GAE/Python application error fix

I need a Google Cloud Platform (Google App Engine) expert with excellent knowledge of Python (current code still 2.7) to help resolve recent application errors that have emerged. These errors caused high latency and excessive data read operations to the server. Case is open with Google and access to development support available. Please see samples of error reports attached. Project assignment will include setting right configuration files and adjustments to optimize Python code and upload of new tested version to the server. If work is satisfactory this can result in handling future enhancement projects.
