This was the first time I ran user interviews and qualitative research. It was a very interesting experience to be able to go deep into the construction site.
When designing, I can put myself in the user's position and imagine more about the situation that the user will face.
In the early stage of the project, I was the UI Designer, and in the later stage, two other designers supported other projects, so I took over the UI/UX maintenance in the later stage, and also accumulated a lot of UX experience.
