Go Lang

Overview

Go Programming training provides highly intensive hands-on training on both Go language and the Go ecosystem, which is packed with real-world guidance. This course lets the participants build Microservices and real-world backend systems using the Go ecosystem. Participants can deep-dive into production systems after completing this training. This training will also provide architecture guidance for building scalable backend systems in Go.
