Shopify Cart Upsell Integration

I'm looking for a skilled developer to integrate cart upsell/orderbump features on my existing Shopify store. Key Requirements: - Implement a strategic upsell feature that triggers during the checkout process to increase the average order value. Ideal Skills: - Proficient in Shopify development and customization. - Proven track record of successful cart upsell/orderbump integrations. - Understanding of e-commerce best practices, particularly in the physical goods sector. I cart want to have surprise product which user can choose. And also one more option: also a product, which I define according to the type of product. In addition, I would like to have a "shipping protection" option that can be selected by the user. Additionally, for the primary product in the shopping cart, I would add below an option to select the same product at say 40% off. All these functions must be integrated in such a way that they can be translated into different languages. Manually in code or via 3rd party applications. It is very important to do this as on one domain / store, I do multiple countries. All this tekts, in the cart, should be compact for translation into other languages. With 3rd part or manually in the code. I will do it myself. I use the Sopify-kalles theme I already have an established Shopify store for my physical goods; I just need to enhance its functionality by integrating upsell features. Your ability to deliver on these requirements will be key in increasing my store's revenue and customer satisfaction. For a better understanding, you can see a screenshot
