From Building Systems to Connecting Systems “Wait… I’m not building an application this time?” When this system development project began, things took a somewhat unexpected turn. In fact, my department did not have that much of a role in the initial development of this system. Why? Because the system itself was already built. This was not a project where we developed an application from scratch. Instead, we were introducing an existing, fully developed system and adapting it to the Japanese business environment.

When a completely new system suddenly enters an existing environment, it inevitably creates an “interface” problem with the surrounding systems that have been running until then. Naturally, those surrounding systems need to be modified as well. “The system is already complete.” That may be true. But from the perspective of the surrounding systems, the reaction is more like: “Wait a minute… this new system just showed up out of nowhere!” And so...

Whoa. The moment I became captivated by a salary figure, the way I saw my entire career as an engineer began to change. The “Full-Stack Engineer” I Admired In the world of engineering, there are many people who quietly and steadily build systems behind the scenes—not just those who stand out or take the spotlight. And engineers tend to be remarkably committed to learning. I was no different. Servers. Networks. Applications. A person who understands each specialized area, can see the bigger picture, and knows what needs to be done—and who needs to do it. Someone who understands the entire development project and can make the system work as a whole. People like that are often called full-stack engineers . Among engineers, they are the people others look up to. I remember going to take difficult IPA IT certification exams in Japan. The exam would take an entire day, and dozens of engineers would gather at the venue. I could almost feel the atmosphere: “Maybe these people are also working ...
