Mobile design system
I created, managed and maintain the sketch library for the mobile team, this helps everyone keep aligned and consistent with Android, iOS and the company guidelines.
I based the design system on atomic design, with each component being able to be broken down into atoms, molecules and organisms.
Take Lego as an analogy one way to approach a Lego project is to simply dump the pieces out onto a table, and rummage through the pile to find the pieces you need. You will get to the same outcome but it can be frustrating and take longer to achieve.
So by taking the time to organize the pieces that make up your final creations allows you to approach the work in a more deliberate and efficient manner.
From here we have the power to create other products from these elements, which keeps consistency in the product.
Basically having a design system will speed up your design process, reduce design debt, consistency across teams and more time to research; usability test & iterate.
