Hello,
I'm excited to share with you the proposal for the UI/UX Designs. I have completed several UI Design projects, kindly check my profile for my recent projects. Or directly message me, so i can send you my recent projects. Currently I am working with Sketch for MacOS. But if you prefer PSD, we can convert it later with photopea.
For milestones, i think it works with payment per screen or 3 screens. Hope you agree with that. Again, please message me first for better communication.
I'm truly excited to be working with you on your projects.
I look forward to your response.
Regards,
