A Shared Language Through Design Systems

I am no expert on the subject of Design Systems but what I am, is bilingual. I grew up in graphics and design was my first language. I moved to development and lived here long enough to start dreaming in code.
What I am is an interpreter fast becoming adept at catching the subtle nuances easily lost in translation, acting as a go-between when designs are switched to code. Focusing on my team's journey on creating the spacing for Zoopla's design systems. I will touch on the:

• communication challenges between design & engineering
• the skills I used to be the bridge between both roles
• process in creating a shared language between the product team, and
• any future improvements I can foresee
