Flask Backend Debugging and Aws Websocket Integration for Ai Call System with Twilio

Description:
We are looking for an experienced backend developer with expertise in Flask, AWS, and WebSocket protocols to debug and optimize our AI-based call system. The system is already operational locally but faces issues in production deployment on AWS EC2.

Current Setup:
Flask Backend: Handles call initiation, callbacks, and WebSocket streaming.
Twilio Integration: Used for initiating calls and streaming audio to our backend via WebSocket.
AWS Deployment: Hosted on an EC2 instance with Nginx as the reverse proxy.
WebSocket Issues: WebSocket connections fail in production; no logs appear from the WebSocket handler on the server.
Tasks:
Debug WebSocket Streaming Issue: Ensure WebSocket connections work as expected in production (AWS).
Nginx Configuration: Review and optimize the Nginx configuration for WebSocket support.
Twilio Integration Debugging: Verify Twilio API configurations and troubleshoot any issues with callbacks or streaming.
AWS Configuration: Ensure proper security group rules, networking, and firewall settings to allow WebSocket connections.
