As a developer with seven years of experience, I have always defined myself as a "backend-only developer." Watching the rapid spread of trends like AI, automation, and solo service startups, I recognized their importance but felt like I was just watching from the sidelines, unable to keep up. Through this course, I finally had the experience—admittedly for the first time in my life—of planning, developing, and launching a service entirely on my own. Although I don't have any users yet, the mere fact that I "released a service I built to the world" has been a massive turning point for me. Beyond just development, I've started thinking about marketing, user perspectives, and service growth based on what I've learned. Moving forward, I plan to actively apply Claude Code not only to development but also to marketing and operations. This course served as a catalyst for me to broaden my horizons, evolving from a developer who is good at technology to one who creates and scales their own services. Thank you sincerely for making this experience possible.
