Visual/UI Designer

We are an early-stage consumer iPhone app looking for a strong visual/UI designer to take a small set of finished iPhone screens and make them pop. You will polish 3-5 iPhone screens to production-grade fidelity using our brand system thoughtfully. Requirements: Strong iPhone/iOS portfolio, Figma-native, comfortable working inside an existing brand system. Bonus if familiar with React Native constraints. Rate is $50 fixed per screen for a 3-5 screen test project, with potential for ongoing work.
