I am a power engineer. Working in the space industry, where the cost of error is high, I got tired of sitting in Excel for hours and mastered full-stack development. In 10 years with Python and web technologies, I have learned the main thing: an engineer does not have to become a programmer, it is enough to take the right tools. This book was born from my experience at the intersection of hardware and interfaces. I believe that a good tool saves years of life.
