dotmailer - product UI redesign

I was assigned to redesign web app interface to create a uniform look and consistence UI. I designed an overall layout in a day and spent a month to finish the project which includes a new pattern library, a new grid layout, a simpler navigation, typography and iconography.

All those elements was created in multi-language, reseller safe and 3rd party integration (SalesForce, Magento and Dynamics) purposes.
