_Epilogue

In an era of collaboration with developers around the world, developers are no longer just people who are good at writing code.
Just as important as the ability to read and write good code is the ability to communicate clearly and persuasively.

This book helps developers adopt English as a "working language" and systematically learn expressions and situations necessary for practical work.
It contains examples that can be encountered in real-world work situations, such as code reviews, bug reports, documentation, issue management, English interviews, and technical presentations.

Additionally, it is designed so that you can practice repeatedly on your own through AI-based tutor systems, videos of actual pronunciation by native speakers, quizzes, etc., so you can expect a learning effect that is different from simple sentence memorization or collections of expressions.

√ Who is this book for?

● Developers and IT majors preparing for a global career
● Professionals who want to overcome vague fears about IT English through practical application
● Readers preparing for career expansion, from English interviews to LinkedIn profile writing
● Job seekers who want to feel confident in their resume, portfolio, and interview preparation
● Learners who want to check their English skills and practice repeatedly with an AI tutor
● Juniors unfamiliar with global collaboration, English commit messages, and open source activities
● Developers who want to 'properly' understand technical documentation
