I recently received mentoring from Grit mentor. This e-book contains the core content of that mentoring. If I were to leave a one-line review, it would be that I gained value beyond the amount I invested. While preparing for a job change, I looked at resumes of fellow developers around me and revised my own resume countless times. However, if you started your developer career in SI, honestly, there isn't much special content worth putting on your resume. Project experiences are all similar, and it's difficult to create a resume that stands out to anyone. That's why many people take bootcamps or online courses to learn new tech stacks in order to increase their resume acceptance rate. I did the same. But from my experience, to be brutally honest, that alone makes it difficult to fundamentally improve the resume itself. This book contains stories about "What can I do with what I have?" instead of "What am I lacking?" The same experience becomes a much more attractive story when you change your perspective. Rather than simply listing technologies like "I developed this," it teaches you how to attractively tell your own story by incorporating your perspective as a developer. I recommend this book to those who are worried because they have SI experience or don't have special projects. You can learn that how you show what you have ultimately makes the difference.
