I need an end-to-end web application, front-end and back-end, that ships production-ready code and is already live on AWS when we shake hands on completion. All development must sit in a clean, well-documented GitHub / GitLab repository so every commit, branch, and pull request is traceable. Core requirement: integrate Exotel’s call-masking API. Calls must flow through virtual numbers, show the correct masked caller ID, and log events (initiation, connection, hang-up, failures) in the database for later analytics. Should future business needs demand it, the codebase must remain flexible enough to swap in Twilio, Vonage, or Plivo without a full rewrite, so keep the telephony layer modular. Deployment target is AWS. A lightweight CI/CD pipeline that builds, runs tests, and promotes to a live environment is part of the scope. Use whichever AWS services make sense—Elastic Beanstalk, ECS, or even a serverless stack—so long as the result is documented and reproducible from the README. Deliverables • Source code in GitHub / GitLab with inline comments and a comprehensive README (setup, environment variables, migration steps). • Working Exotel integration that can be demonstrated with test numbers in both staging and production. • AWS deployment, accessible over HTTPS, with logs and metrics visible in CloudWatch. • Brief hand-off session or screencast walking through the repo structure, deployment pipeline, and how to extend the telephony module. Acceptance criteria: all automated tests pass, Exotel masking works with two test numbers, and the production URL is live on AWS at the end of the project.

Hi there, Building a production-ready application with a "modular-first" mindset is exactly how I approach development. I understand that for this project, the Exotel integration is the core, but the architectural flexibility to swap providers is the long-term value. How I will deliver your project: Modular Telephony Layer: I will implement a Provider Pattern (Interface-based) for the telephony module. This decouples the business logic from the Exotel SDK/API. If you decide to switch to Twilio or Plivo later, you’ll only need to write a new implementation of the interface without touching the core application logic. Production-Ready Backend: I’ll build a robust API (Node.js/TypeScript or Python/FastAPI) that handles Exotel webhooks to track call events (initiation, hang-ups, failures) in real-time, persisting them to an AWS RDS instance for your analytics. AWS Infrastructure as Code: I won't just manually click buttons in the console. I will set up a GitHub Actions/GitLab CI pipeline that automates testing and deployment to AWS (ECS or Elastic Beanstalk). This ensures that the environment is reproducible and the README is an actual source of truth. Observability: I’ll configure CloudWatch logs and basic health metrics so you have full visibility into the application’s performance and call success rates from day one.
