01 / Laying The Foundation

Joining Seismic through an acquisition I worked closely with leadership to audit the systems between Percolate and Seismic and find the right solution that would set Seismic up for success going into a high growth phase of the business. Finding that Percolate had a great foundation we used that as the new foundation for the Mantle Design System as we acquired two more companies. Our Sr. designer Sakshi Aurora from Percolate focused all her energy into supporting and building the system that would fuel Seismic's full suite of products today.
