Working as the only UX/UI person at my company, I had to solve every challenge on my own, and this course was incredibly helpful. I was able to clearly understand how to actually build and utilize a design system, and I was particularly impressed by the systematic approach to managing colors, typography, spacing, and themes using Variables. The real-world examples from actual work situations made it much easier to understand, and those aspects have greatly helped me communicate with developers in my actual work. I would highly recommend this course not only to designers who are introducing a design system for the first time, but also to those who are already using one but want to make their structure more systematic.
