Backend Master Class [Golang + PostgreSQL + Kubernetes]

In this course, you will learn step–by–step how to design, develop and deploy a backend web service from scratch. I believe the best way to learn programming is to build a real application. Therefore, throughout the course, you will learn how to build a backend web service for a simple bank. It will provide APIs for the frontend to do the following things:

Create and manage bank accounts.

Record all balance changes to each of the accounts.

Perform a money transfer between 2 accounts.

The programming language we will use to develop the service is Golang, but the course is not just about coding in Go. The course is divided into 4 main parts:

In the first part, you will learn deeply about how to design the database, generate codes to talk to the DB in a consistent and reliable way using transactions, understand the DB isolation levels, and how to use it correctly in production. Besides the database, you will also learn how to use docker for local development, how to use Git to manage your codes, and how to use Github Action to run unit tests automatically.

In the second part, you will learn how to build a set of RESTful HTTP APIs using Gin – one of the most popular Golang frameworks for building web services. This includes everything from loading app configs, mocking DB for more robust unit tests, handling errors, authenticating users, and securing the APIs with JWT and PASETO access tokens.
