You have come to the right place for an urgent project like this. As a seasoned Shopify developer, I understand the value of time and the immediate needs of dexterity for your business. Having worked with Shopify since its inception in 2010, I am highly skilled and efficient in carrying out customizations and installing apps on the platform.
My expertise traverses many key areas relevant to your project. For instance, regarding the addition of an affiliate app, I am well-versed with such integrations and can assure you clean, seamless integration that would enhance your store's functionality. Additionally, for implementing an enticing campaign using a lead capture function in the header with a discount offer, I have ample knowledge working with databases for such forms' storage and mailing system configurations.
Quality copy placement is absolutely crucial for an engaging website, and I'm confident in my ability to execute this task flawlessly. Drawing on my experience designing websites, working with HTML, CSS, as well as various CMS systems (including Shopify), I can ensure that all texts are neatly transferred without compromising their alignment or visual aesthetics.
