GoLang Workshops

Why take this course

If you want to build efficient, reliable, and scalable applications, this training will equip you with the practical skills needed to effectively use the Go language. With it, you’ll be able to proficiently handle the language’s complex mechanisms, test your code, and implement effective services, accelerating the development of your projects.

What you'll learn

• Create correct code in Golang using advanced features. This includes creating your own robust data types, implementing concurrency mechanisms, and handling errors and time-based events effectively.
• Test your code using the complete set of tools offered by Go. You’ll master unit testing, benchmarking, and fuzzing to ensure your applications are reliable and performant.
• Implement efficient RESTful services and analyze their performance.
• To practically use relational databases.

Certification & Exam

Upon completion of the training, you will receive a certificate of participation, confirming your skills in using the Go language. There is no final exam—all you need is active participation in the classes.
