I’m looking for an experienced Shopify developer to improve my website by adding a popup and configuring an online chat feature. The popup may be used for promotions, announcements, or email collection. The online chat should allow visitors to easily contact us in real time. The developer should ensure the features are fully responsive, work smoothly on desktop, tablet, and mobile, and match the existing design and branding of the website. Attention to detail, clean implementation, and experience with Shopify apps are important.
