Where we'll start:

We will start by creating a simple TCP-server to get acquainted with the net/http package and understand the basics of network interaction in Go.

What you will learn:

Then we will delve into the architectural principles of building reliable and modular web applications in Go. The project will develop step by step, and you will go through key topics such as:

  • Handling HTTP requests
  • Creating custom middleware
  • Database integration
  • Optimizing queries and database interaction
  • Rate limiting
  • Preparing for cloud deployment and handling real traffic

What this course will give you:

This course is not just a step-by-step guide - it is a comprehensive training aimed at developing a deep understanding of backend systems, mastering industry best practices, and creating secure, scalable, and maintainable APIs ready for production.

It is perfect for those who want to go beyond template solutions and learn how to develop real backend services in Go that are ready for real-world projects.
