@AhyoungRyu, Thanks for review and suggestions!
Sure, I can change the border color in Technologies section and, I can
remove icons in Deployments section.
IMO, about Deployments section, actually the current structure is good to
me (including icons).
And especially the buttons, it would be better to keep the current
structure to match the buttons in the above technologies.

How about this? :slightly_smiling_face:
