Scalable, secure backend systems and APIs built for the real world.
I design and implement production-grade REST APIs, microservices, and backend systems using ASP.NET Core Web API and Node.js/Express. Every API is built around clean architecture principles — testable, documented, and ready to scale.
Technology Stack
API Design & Architecture
A well-designed API is the foundation of any successful application. I follow REST best practices and clean architecture patterns to ensure your API is intuitive, consistent, and easy to evolve.
- RESTful API design with clean resource modeling
- Layered architecture (Controller / Service / Repository)
- CQRS pattern for complex query separation
- Comprehensive error handling and logging
- Swagger / OpenAPI documentation generation
- Versioning strategy for long-lived APIs
Security & Authentication
Security is not an afterthought. Every API I build is hardened against common attack vectors and follows the principle of least privilege throughout.
- JWT-based authentication with refresh token rotation
- Role-based access control (RBAC)
- Rate limiting and request throttling
- Input validation and sanitization
- CORS configuration and HTTPS enforcement
- Audit logging for sensitive operations
Performance & Scalability
I build backends that handle real-world load. This means careful database query optimization, response caching, and infrastructure designed to scale horizontally when needed.
- Database query optimization and indexing strategy
- Response caching (in-memory and distributed)
- Async/await throughout for non-blocking I/O
- Connection pooling and resource management
