Figma & UI Designer

I need someone with experience in Figma to design and update the user interfaces (UIs) for our website. The mockups have been created, but the designs will require frequent updates as UX brings in new requests on a daily basis. The development process will be ongoing, with a focus on delivering short-term goals in each sprint.

Requirements:
-Proficiency in Figma for designing and updating UIs.
-Previous experience or certificates in web design.
-Experience or certificates in UX/UI design.
-Familiarity with Agile methodology, sprints, and Scrum.
