Senior Shopify Developer Needed – Enterprise OS 2.0 Rebuild + Existing Site Audit

@visionvivante

Hello, I understand you’re looking for a senior Shopify developer to audit your existing store, fix structural issues, and lead a full enterprise-level rebuild on Shopify OS 2.0 with a strong focus on performance, scalability, and advanced automation. Key expertise I bring: • Shopify OS 2.0 enterprise-level rebuilds and migrations • Deep Liquid, CSS, and data structure optimisation • Performance tuning for 90+ PageSpeed (mobile-first focus) • Advanced collection architecture and mega menu systems • Shopify Flow automation and backend logic setup • App integration and configuration (Search, shipping, feeds, localisation, emails) • UX-focused B2B and loyalty system implementation My approach: I will start with a full technical audit of your current store to identify performance bottlenecks, theme structure issues, and app conflicts. Then I will redesign the architecture in OS 2.0 using modular sections, optimized Liquid code, and clean data flow. After that, I will focus on speed optimization, app configuration, and automation setup to ensure the store is scalable and stable under enterprise load. I have worked on Shopify builds involving advanced collections, multi-app ecosystems, and performance-heavy stores, and I can share relevant examples upon request.

@Friends4it

I've rebuilt multiple enterprise Shopify stores from legacy themes to OS 2.0 with full data architecture planning, and this is exactly the type of project I handle best — not just a theme swap, but a proper structural rebuild. Here's how I'd approach your project: Phase 1 — Audit: Full technical audit of your current store covering theme code quality, page speed bottlenecks, app conflicts, Liquid inefficiencies, and data architecture (metafields, product organization, collection logic). Phase 2 — OS 2.0 Rebuild: Build a clean OS 2.0 theme with sections everywhere, optimized Liquid templates, and a modular architecture designed for 90+ Mobile PageSpeed. Implement Mega Menu with nested collections, Automated Collections with proper tagging taxonomy, and B2B portal structure with Loyalty integration. Phase 3 — App Ecosystem: Configure Searchanise, Redirectify, EasySearch, Transcy (multilingual), Advanced Shipping Rules, Google Shopping Feed Pro, and Orderly Emails. Each app properly integrated without performance conflicts. Phase 4 — Shopify Flow: Set up native automation workflows for order processing, inventory alerts, customer segmentation, and marketing triggers. I work in clean, well-documented Liquid and CSS — no bloated page builders. Happy to share examples of enterprise-level Shopify stores I've built and scaled.

@codefusion53

Hi, Your project is clearly an enterprise Shopify rebuild, not a standard theme setup, and that aligns well with my experience in Shopify architecture, Liquid development, large catalog management, and performance optimization. I have worked on high SKU ecommerce environments involving structured collections, advanced filtering, app ecosystem integrations, multilingual setups, and migration workflows into Shopify OS 2.0 architectures. My approach is always data first, focusing on scalable collection logic, clean metafield structures, optimized Liquid rendering, and long term maintainability. For PageSpeed, I focus heavily on reducing app bloat, lazy loading media, optimizing Liquid loops, minimizing render blocking scripts, controlling third party assets, and creating lightweight section architecture to consistently achieve strong mobile scores. I also have experience configuring apps such as Searchanise, Transcy, Redirectify, Google Shopping Feed Pro, shipping automation tools, and Shopify Flow for operational automations and catalog workflows. I would be interested in reviewing the current store structure, SKU volume, app stack, and migration challenges in more detail. Best, Justin

Hi, I am an experienced senior Shopify developer and can handle your full OS 2.0 enterprise rebuild, including a complete audit of your existing store, identifying and fixing performance and structural issues, and migrating everything to a new Shopify OS 2.0 setup with a scalable, clean architecture.

@Herculesz

Hi I can review your current Shopify store, fix the urgent issues, and lead the rebuild into a clean Shopify OS 2.0 architecture for a high-SKU enterprise catalog. For large migrations, the main technical risk is poor data structure, broken redirects, slow collection logic, app conflicts, and theme bloat that prevents a 90+ mobile PageSpeed score. My approach would be to audit the existing store first, clean the product/variant/metafield/collection architecture, then rebuild the Liquid/CSS layer with performance, SEO, redirects, and app compatibility in mind. I have experience with Shopify OS 2.0, Liquid, CSS, large catalog migration planning, automated collections, mega menus, B2B flows, loyalty setup, Shopify Flow, and app configuration. For PageSpeed, I would focus on lean section code, optimized media, reduced app scripts, critical CSS, lazy loading, font cleanup, theme profiling, and removing render-blocking assets. I can configure or troubleshoot apps such as Searchanise, Redirectify, EasySearch, Transcy, Advanced Shipping Rules, Google feed tools, Orderly Emails, and Shopify automation workflows based on the required store logic. This is the type of rebuild where the data model, theme performance, and app ecosystem need to be planned together, not handled as separate theme edits. Thanks, Hercules
