Background We run a Shopify store with a heavily customized theme. We recently had a developer work on cleaning up the variant selection logic. The work is partially done but not production-ready. We need an experienced Shopify developer to take over and finish it properly. Current State - _updateOptionAvailability was rewritten and appears to work correctly - Global event listener workarounds have been removed from the JS - A custom Select2-based dropdown was introduced as a parallel variant selection layer on top of the native theme system – this is where the problems start Problems We Are Seeing We are not developers, but based on what we observe and what we can see in the code, the following issues exist. On pageload the wrong variant state is loaded. Unavailable variants appear pre-selected, the add-to-cart button shows when it shouldn't, and the sold-out/notify state is not applied correctly. Once you manually switch variants and come back, everything displays correctly – so the issue is isolated to initial pageload. We believe the custom dropdown does not check availability when selecting the default option on init, and the native theme never receives a proper trigger to re-evaluate the button state after the initial selection is set. Additionally, availability status labels appear to not update dynamically when switching variants. Expected Files Involved - [login to view URL] - [login to view URL] - [login to view URL] Goal We want a clean, error-free theme with a reliable variant logic that works in every case – on pageload, on variant switch, on all devices. No workarounds, no open issues. It just needs to work and run cleanly. The developer should assess the full codebase independently, identify all related issues, and deliver a proper solution. We are open to any approach as long as the result is stable, fast, and maintainable. Requirements - Strong Shopify theme development experience (Liquid, JS) - Experience with variant change events and native theme initialization - Comfortable working in complex, customized legacy theme code - Clean code delivery – please include your approach and relevant experience in your application

Hello there How do you want to handle the initialization of the custom dropdown to ensure correct variant availability on page load? What is your preferred method for dynamically updating availability status labels across all devices? Ensuring the initial variant state loads correctly is tricky because the custom dropdown and native theme must sync perfectly without delays. Updating availability labels dynamically is challenging due to the complex interactions between custom scripts and Shopify's theme events. I will carefully review the full codebase, fix event triggers, and ensure smooth variant status updates with clean, maintainable code. I would be happy to discuss further on chat. Best regards.
