My design style preference is bold and colorful, and I need certain specific functionalities and features which include advanced product filtering. Ideally, I would prefer a freelancer who has a vast amount of experience in SKU-based e-commerce websites or online stores. The freelancer should possess strong technical skills and understand the importance of best practice web design standards, as well as ensuring the smooth running and optimal performance of the website. Furthermore, this freelancer should be able to develop custom apps and features, as well as integrate with a payment gateway.
