Now is truly an era where anyone can create their own service in just one day. While the previous Vibe Coding workshop focused on directly experiencing what Vibe Coding is all about and aimed for everyone to complete and deploy the front-end (visible pages) of the service they wanted to create, this workshop goes beyond simply creating a visible service. It places significant emphasis on a development approach that involves concretely imagining actual users and focusing on 'who will use this service and why.' Through the workshop, participants will naturally learn how to clearly define their target users and the problems to solve while creating their own services. It's perfectly fine if you're new to Vibe Coding! Even if you don't know coding or development, it's more than enough! Rather than simply following along, experience creating a truly usable service yourself in this workshop!
