REST & GraphQL APIs
We build interfaces between systems. Documented, secured, and scalable APIs that connect anything to anything.
API Development.
A good API is invisible — it connects applications, services, and data without friction. We build REST APIs with OpenAPI/Swagger and GraphQL with Apollo Server.
Every API we deliver has: interactive documentation, JWT/API key authentication, rate limiting, input validation, standardized error handling, and monitoring.
We integrate systems that were never designed to communicate: ERP with CRM, online store with warehouse, mobile app with legacy backend.
Key benefits.
Automatic Documentation
OpenAPI/Swagger generated automatically from code. Developers test endpoints directly from the browser. Zero confusion.
Multi-Layer Security
JWT, API keys, rate limiting, CORS, input validation. Each layer protects against a different type of attack.
Versioning & Backward Compatibility
The API evolves without breaking existing integrations. URI or header-based versioning.
Monitoring & Analytics
Every request is logged: latency, status code, payload size. We identify bottlenecks before they become problems.
Use cases.
FAQ.
REST for simple and public APIs. GraphQL for applications with complex data and nested relationships. We often combine both in the same project.
Yes. We build middleware that transforms old formats (SOAP, XML) into modern REST APIs. Zero modifications to the legacy system.
JWT for authentication, RBAC for authorization, rate limiting for abuse prevention, mandatory HTTPS, input validation on every endpoint.
