Hi there! I haven’t introduced myself yet, as I haven’t had the chance. My name is Harutyun {ha.root.eeoon}, and I’m a Software Engineer and passionate Golang Developer. I really adore the language and enjoy working with its toolchain. I’ve been working with Go for the past five years. Before switching to Golang, I worked as a Full Stack Developer, with PHP as my main backend language and JS + jQuery for the frontend.
At that time, I noticed that many companies were transitioning to Golang from Ruby, NodeJS, and PHP to improve latency, introduce concurrency, and enable background task execution for their products. The first article I came across was on Shopify’s blog, explaining how switching to Golang improved their service latency by 80%. I was fascinated by the article and began reading up on references, language concepts, and Golang’s official blog to better understand the language.
After PHP, Golang felt like a breath of fresh air—everything was fast, incredibly fast. I remember the first program I wrote: a file checksum validator for some open-sourced NASA data from the Apollo mission. It involved a collection of five files, each around 2GB in size. Seeing an execution time of 1.4 seconds blew my mind. At that moment, I knew I had to switch my stack to Golang to create and develop awesome software.
In this article, I want to share some resources that helped me become a Golang Engineer and continue to help me develop new skills while staying up to date with the latest technologies.
Books: The Saint Triada
Get Programming with Go by Nathan Youngman and Roger Peppé
If you’re just getting started with Go and want a book that makes the learning process easy and approachable, I highly recommend “Get Programming with Go” by Nathan Youngman and Roger Peppé. This book is perfect for beginners because it really focuses on the basics without overwhelming you with too much information at once. What’s great about this book is how clearly it explains everything. It starts right from the ground up, walking you through the core concepts of Go step-by-step. You’ll learn the essentials like how to declare variables, use loops, and write functions, but the authors do it in a way that’s super accessible—even if you don’t have a ton of programming experience.
If you’re new to Go or even new to programming in general, “Get Programming with Go” is one of the best places to start. It’s designed to help you build a strong foundation in the language without feeling lost or frustrated, and by the time you’re finished, you’ll have a solid understanding of how Go works. One thing I really liked is that the book doesn’t assume you already know a bunch of other programming languages. It’s written in plain language and focuses on helping you understand Go’s syntax and structure in a simple, straightforward way. It also covers Go’s unique approach to things like error handling and memory management, but again, in a way that’s very beginner-friendly.
Learning Go by Jon Bodner
If you’ve already gone through “Get Programming with Go” and are looking to take your Go skills to the next level, I highly recommend following up with “Learning Go” by Jon Bodner.
