GoLang (Go Programming Language)

Location: On-Site or Online
Pricing: $1,250 per seat (6-seat minimum)
Length: 4 Days

Course Summary

GoLang is a practical, hands-on course designed to teach students how to build fast, reliable, and maintainable software using the Go programming language.

Students learn Go from a systems and production mindset—focusing on simplicity, concurrency, correctness, and performance. The course emphasizes real-world Go patterns such as explicit error handling, composition over inheritance, concurrency with goroutines and channels, and building production-ready command-line tools and services.

By the end of the course, students are comfortable reading, writing, and debugging Go programs and understand how Go is used in modern infrastructure, cloud-native platforms, and backend services.
