A robust API starts with the right architecture and proven code. We offer a full cycle of API development and testing, including design, documentation, moc writing, unit and load tests, assembly and release automation.
Our goal is to make every integration predictable, secure and easily scalable.
What is included in the development process
| Stage | Description |
|---|---|
| API Design | REST/GraphQL/OpenAPI specifications, endpoint structure |
| Documentation | Swagger/Redoc, model descriptions, sample queries and responses |
| Mock servers | Generating fake responses to accelerate front-end development |
| CI/CD Pipelines | Automatic assembly, tests and API calculation |
API Test Types
| Type of tests | Appointment |
|---|---|
| Unit-tests | Checking the business logic of individual methods |
| Integration-tests | Checking the interaction between components and the database |
| Contract-tests | Verifying that API meets client expectations (e.g. Pact) |
| Load-tests | Load testing (k6, JMeter) |
| Security-tests | Checking API for vulnerabilities (OWASP, fuzzing, tokens) |
Tools and technologies
OpenAPI, Swagger, Postman
Jest, Mocha, Pytest, PHPUnit
Docker, GitLab CI/CD, GitHub Actions
