  • Mentor junior developers while demonstrating leadership. 

Skills

  • Hands-on experience with Docker and Kubernetes, as well as developing applications using microservices architecture within cloud platforms such as Microsoft Azure, AWS, or Google Cloud. 

  • Solid knowledge of computer networking principles. 

  • Experience with network service technologies such as HTTP, gRPC, TLS, REST APIs, and OpenTelemetry.
