This is my proposal process step by step:

I will start by researching your product, competitors, and the market. If you already have a website or app, I will also do an audit to understand what's working and what are our opportunities for improvement.

In this step, I will create low-fidelity wireframes for your product, defining the content placement and screen order. This way, we can validate the initial design before moving forward with the high-fidelity wireframes.

Now that the sketches are validated, it's time to see the visuals with the high fidelity version of the wireframes.

If necessary, I'll also create a clickable prototype for your product, including all the interactions and animations.

If you have access to real users, I'll perform user testing to validate the design, and apply feedback if necessary.

You also receive a guide, which includes typography, color styles, all UI components (buttons, inputs, etc.) in one design system.
