Backend Development

Using Node.js for fast and efficient server-side development. The Express framework for creating robust APIs and web applications.

Designing clean and intuitive RESTful APIs. Following standards for ease of integration and maintenance.

Implementing secure authentication using JWT. Protection against common vulnerabilities like XSS and CSRF.

Designing and developing microservices architecture for complex and high-load applications. Docker and Kubernetes for container management.

Robust backend technologies for scalable and secure server-side applications.

• Node.js - JavaScript runtime environment
• Express - framework for building web applications and APIs
• PostgreSQL - powerful relational DBMS
• Prisma - modern ORM for Node.js and TypeScript
• Redis - in-memory data store for caching
• Docker - containerization platform

Proven methods for backend development and architectural patterns.

• Clean architecture for separation of concerns
• Middleware pattern for logging, authentication
• Input validation to prevent errors
• Async programming with async/await
• Testing strategy unit and integration testing
• Graceful shutdown for proper termination

Our backend development experience includes diverse project types.

• High-load APIs for mobile and web applications
• Payment systems and gateway integrations
• Real-time platforms chats, notifications
• Business systems with distributed architecture

Key principles for building maintainable backend systems.

• Separation of Concerns clear module boundaries
• Dependency Injection for testability
• Middleware pattern for request processing
• Repository pattern for data access
• Service Layer for business logic
• Error handling middleware

We create reliable and scalable APIs with modern standards.

• RESTful APIs with proper HTTP methods
• GraphQL for flexible data queries
• WebSocket for real-time communication
• API versioning for backward compatibility
• Documentation with OpenAPI/Swagger
• API testing with Postman/Newman

Essential security measures and performance optimization techniques.

• Authentication and authorization with JWT
• Input validation and sanitization
• Rate limiting for DDoS protection
• Caching with Redis
• Performance monitoring real-time metrics
• Error logging and tracing
