At راگن هداد نیبار, I designed and implemented NestJS services and REST APIs across production services, and developed real-time communication with Socket.IO and WebSockets.
At لایس هداد دنمشوه, I designed production NestJS services and PostgreSQL schemas, and implemented background processing with BullMQ and Redis. I also handled much of the authentication work and gained hands-on experience with gRPC, oRPC, and CI/CD.
On rest-pro, I designed a layered Go REST API with PostgreSQL persistence and access/refresh-token authentication. I also implemented concurrency-aware components, integration tests, and Docker-based deployment.
