I understand that you want to add the same "choose customization" product page feature on your new Shopify website that you are using on your this website. I can also confirm that my portfolio contains many examples of my work that demonstrate my expertise in UI/UX design, web development, and app development.
I would be delighted to work on your project! With my extensive knowledge in UI/UX design, web development, and app development, I am confident that I can provide the greatest service for your needs. Specifically for this project, I estimate that it would take me less than 10$ to complete the task. In addition to this price estimate being significantly below the budget you have set for the task, I also have experience in responsive design principles for seamless user interactions across various devices and screen sizes as well as incorporating brand guidelines and visual aesthetics into my work. Furthermore, I stay updated with the latest web development trends and technologies so that I can provide top quality service for you.
