Communication Platform API
Enterprise-grade REST API with comprehensive test coverage
A communications company needed a robust backend API to power messaging, notifications, and user management across their product suite.
The Challenge
A communications company needed a robust backend API to power messaging, notifications, and user management across their product suite. Their existing API was poorly documented, had no automated tests, and deployments frequently caused outages. They needed enterprise-grade reliability with comprehensive test coverage and automated deployment pipelines.
Our Solution
We rebuilt the API from the ground up with Django REST Framework, implementing clean endpoint design with versioning, pagination, and rate limiting. Comprehensive unit and integration tests cover 95% of the codebase, with automated test runs on every pull request. The API is containerized with Docker, orchestrated with Kubernetes, and deployed through fully automated CI/CD pipelines that include linting, testing, security scanning, and staged rollouts.
The Results
Achieved 95% test coverage with 800+ automated tests across unit and integration layers
Zero production outages in 12 months since the rebuild went live
API response times averaging 45ms at the 95th percentile under load
Technical Approach
Django REST Framework was chosen for its battle-tested serialization, authentication, and permission framework. API versioning ensures backward compatibility as the platform evolves. The CI/CD pipeline runs on GitHub Actions with Docker layer caching for fast builds. Test coverage is enforced as a merge gate — PRs that drop below 90% are automatically blocked.
