API Contract and Architectural Design
Endpoints, data types, error codes, versioning strategies (v1/v2), and consumer layers are defined.
SOFTWARE SOLUTIONS
Backend and API Development Services
Backend and API development is a service that presents business rules, data access architecture, authentication mechanisms, and system integrations as high-performance, secure, and sustainable services.
What is Backend and API Development Services?
Simply writing a working code block is insufficient for a corporate-scale API infrastructure. Misconceived data models, inadequate authorization layers, and overlooked scalability needs can lead to serious security vulnerabilities and performance bottlenecks as the system grows.
In our development processes, API contracts (OpenAPI/Swagger), standardized error models, object-level authorization (BOLA protection), idempotency for repeated requests, overloading protection (rate limiting), and end-to-end observability (logging/metrics) are designed from the ground up. Depending on the project's data consistency and consumer needs, RESTful, GraphQL, gRPC, or event-driven integration architectures are applied.
Service scope
Security and Authorization Tightening
Authentication (JWT/OAuth2), authorization (RBAC/ABAC), input validation (input sanitization), and abuse protections are integrated.
Core Development and Integration
Business rules, database access layers (ORM/SQL), asynchronous background jobs (background jobs/queues), and external service connections are coded.
Operation, Testing, and CI/CD Preparation
Unit/integration tests, API documentation, log/metric integrations, and automated deployment processes are prepared.

Frequently asked questions
Should we prefer REST API or GraphQL in our project?
It depends on the need. REST is ideal for caching, simplicity, and a broad ecosystem support. GraphQL provides advantages for mobile/web applications with complex data relationships and where the client needs to select exactly the data it requires.
How is the security of API endpoints ensured?
Security is achieved through identity verification (AuthN) and authorization (AuthZ), along with object-level access control, data validation (input sanitization), rate limiting (request throttling), secret management, and audit log records.
Can new API services be added to an existing monolithic system without downtime?
Yes. After reviewing the existing code and database structure, new services and API endpoints can be incrementally added using a compatibility layer (adapter/facade) or the Strangler Fig pattern.
