Aaron Torres received his master's degree in computer science from the New Mexico Institute of Mining and Technology. He has worked on distributed systems in high-performance computing and in large-scale web and microservices applications. He currently leads a team of Go developers that refines and focuses on Go best practices with an emphasis on continuous delivery and automated testing.

Aaron has published a number of papers and has several patents in the area of storage and I/O. He is passionate about sharing his knowledge and ideas with others. He is also a huge fan of the Go language and open source for backend systems and development.

Eduard Bondarenko is a software developer living in Kyiv, Ukraine. He started programming using BASIC on ZXSpectrum a long time ago. Later, he worked in the web development domain. He has used Ruby on Rails for over 8 years. Having used Ruby for a long time, he discovered Clojure in early 2009, and liked the simplicity of language.

Thank you for choosing this book! I hope it will be a handy reference for developers to quickly look up Go development patterns. It is meant to be a companion to other resources and a reference that will hopefully be useful long after reading it once. Each recipe in this book includes working, simple, and tested code that can be used as a reference or foundation for your own applications. The book covers a range of content from basic to advanced topics.

This book is aimed for web developers, programmers, and enterprise developers. Basic knowledge of the Go language is assumed. Experience with backend application development is not necessary, but may help understand the motivation behind some of the recipes.

This book serves as a good reference for Go developers who are already proficient but need a quick reminder, example, or reference. With the open source repository, it should be possible to share these examples quickly with a team as well. If you are looking for quick solutions to common and not-so-common problems in Go programming, this book is for you.
