I have developed all sorts of backends for over 5 years. I heavily use Golang and Node.js for the best performance. I can create state of the art services for your needs from simple monoliths to complex microservices. I am very skilled at the following technologies; REST APIs Internet Protocols (HTTP, GRPC) Authentication Mechanisms (Oauth, Session Auth, JWT) Domain Driven Design CLI Tools CI/CD Pipelines Docker, Kubernetes
