UX/UI Designer (CRM and Systems) Needed.

We are looking for a UX/UI Designer to improve the user experience and efficiency for an existing CRM or system. This could include a Salesforce, HubSpot, or custom-built system. The main goal of this project is to modify the existing UX/UI design, rather than starting from scratch. I want to make sure that any changes to the UX/UI provide my users with a smooth, intuitive experience and help them to achieve their goals. Additionally, I want to ensure that customer engagement and satisfaction is increased as well as enhancing the visual appeal and branding associated with the system.
