BigCommerce Developer Needed – Mega Menu Implementation

We need a developer to build a mega menu for our BigCommerce store. We already have a mega menu draft on our WordPress site (screenshots provided), but we haven't been able to replicate the same functionality on BigCommerce. We're looking for someone experienced with BigCommerce's Stencil theme framework to implement a matching mega menu on our storefront. Scope of work: Build a mega menu for our BigCommerce storefront navigation, matching the structure/style shown in the WordPress screenshots we'll provide Multi-column layout, category images/icons, and featured links or promo blocks within dropdowns Fully responsive (desktop, tablet, mobile — likely a simplified/collapsible version on mobile) Editable/manageable without needing a developer for future content changes, if possible (e.g., via theme editor, navigation menu settings, or a lightweight custom app) Cross-browser testing and QA before going live What we're looking for: Proven experience customizing BigCommerce Stencil themes (please share past examples of mega menus you've built on BigCommerce) Comfortable with Handlebars, SCSS/CSS, and BigCommerce's theme structure Clear communicator, comfortable with async updates and quick turnaround Bonus: experience with headless BigCommerce setups, if relevant to our theme Deliverables: Fully functional, responsive mega menu live on our BigCommerce storefront, matching the provided reference screenshots Brief documentation on how to update menu items/categories going forward
