Golang for Backend Developer

About the instructor

Phu, Tran Phong Developer and Instructor

I'm Phu, I'm a developer with a passion for teaching. I'm an academic advisor and instructor at Nordic Coder. My expertise and skills are in big data, distributed systems, continuous deployment. I have been teaching many courses about backend and frontend such as Golang/Nodejs/PHP, ES/MySQL, and Reactjs/Angular. I've helped students learn to code, improve their skills. I've been invited/collaborated by companies such as ABC to build the courses for training their employees.

I spend most of my time researching the latest methodologies, technologies, skills which should be have for developers to help them learn to make code better, code for fun and love, and make hard concepts easy to understand.

Welcome to my course, I am on way to help you.

About this course

This course is designed to get you up and running as fast as possible with Go. We'll quickly cover the basics, then dive into some of the more advanced features of the language.

After finishing this course, students will be able to learn how to:

• Build high-performance concurrent programs with Golang
• Build modern programs with Golang and its ecosystem such as CI/CD, GRPC
• Build their own programs with hands-on mentoring from the instructor

• Deploy a CI/CD for note services with Jenkins/or Gitlab
• Overview and requirements of the Final Project
• Review and feedback on the course
• Exercise: Apply CI/DC to topic 3
• Homework: Apply Elasicsearch APM to topic 3

Topic 6

• Build your own open-source software
• Build a helper lib (ex: porting underscore)
• Or build an HTTP router
• Or build a (micro) service to generate fake data
• Or build an application with your own idea

Pre-work

A mini project to demonstrate students’ knowledge at input level

• With a given URL of news website (Eg vnexpress.net, thesaigontimes.vn,...), create a crawler that:
• Task 1: Can fetch the whole data from a news website then parse the data into specific piece as: title, published date, summary, body and author
• Task 2: With any URLs found in the previously fetched data, repeat the task 1 until reaching maximum of 5 levels.

Final project

The final project is up to students with mentoring from instructor. The objective of the project is to:

• Demonstrate understanding of Golang and its ecosystem.
• Apply knowledge gained during the course by building an application/program such as a helper lib (ex: porting underscore), an HTTP router, a (micro) service to generate fake data or create API for blog, e-commerce, Todo app, etc.
