API & Backend Development | REST, GraphQL, NestJS
Expert in backend and API development, I design robust and scalable architectures with NestJS and Symfony. Whether it's a REST API, GraphQL or microservices architecture, I ensure your backend is performant, secure and well-documented.
Backend Services
- REST API with OpenAPI/Swagger documentation
- GraphQL API with typed schema
- Microservices architecture with RabbitMQ/Kafka
- Authentication and authorization (JWT, OAuth2)
- Third-party service integration (Stripe, SendGrid, AWS)
- Unit and integration testing
