Experienced Shopify Developer Needed for Professional E-commerce Store Setup and Customization

We are seeking an experienced Shopify developer to build and customize a professional online store for the Swiss market. We have an existing Shopify account, domain, and a professional theme that needs to be tailored to our brand. The primary goal is to transform the theme into a modern, trustworthy, and user-friendly e-commerce platform without developing everything from scratch.

The store will feature approximately 150 products, requiring organized collections, robust search and filter functionalities, and optimized product pages. The design must be fully responsive across all devices, with efficient image compression for fast loading times. Key functionalities include a seamless cart and checkout process, integration of Swiss-specific payment and shipping options, basic SEO implementation, Google Analytics setup, and proper cookie/privacy settings. Mobile performance optimization is also crucial.

Prior to launch, the complete store must undergo thorough testing, including the entire shopping and checkout process, to ensure all functionalities work flawlessly and any final issues are resolved. Product data, images, and detailed information will be provided once they are ready.

This project will commence after our internal company setup and product preparation phases are complete. We are looking for a freelancer with proven Shopify experience, who can provide an estimate of working days and references, and potentially offer post-launch support.
