Steps for completing your project
After purchasing the project, send requirements so Javed can start the project.
Delivery time starts when Javed receives requirements from you.

Revisions may occur after the delivery date.
Understand the business goal, target audience.
Will understand the requirements of the app and target audience to make the UI/UX according to that and for better user experience and save time for trial and error.
Start the UI/UX Design in either Figma or Adboe illustrator.
Once I will have the understanding of the project and target audience related knowledge I will start working on the setting up the foundation for the UI like, color scheme, how buttons and other controls will be looks and then start on the UI screen.
