Santo Stefano di Rogliano: Your Shopify Plus experience, without limits

We analyze business requirements and design a modular backend architecture that supports multi-store, headless, and ERP integrations at scale. We use Shopify Functions, advanced Liquid, and the Storefront API to create customized experiences, while Node.js microservices manage complex logic outside the platform. We implement CI/CD pipelines with GitHub Actions, automated testing (unit, integration, end-to-end), and blue-green deployment strategies to ensure zero-downtime updates during traffic peaks. Finally, we monitor latency, error rate, and PCI compliance with tools like New Relic and Sumo Logic, constantly optimizing the platform for maximum performance.

We create responsive interfaces based on consistent design systems, using Figma and Web Components to ensure consistency across all touchpoints. We leverage Liquid server-side rendering combined with CSS Grid and custom CSS properties to optimize time-to-first-paint and the perception of speed on mobile devices. Through heatmap analysis, session replay, and usability testing, we iterate on micro-interactions and micro-copy to guide users toward key conversions, implementing CSS micro-animations to increase engagement without sacrificing performance. We customize checkout with Shopify Scripts and conditional Liquid, reducing steps and improving the funnel by 15-20%.

We implement a data-driven conversion optimization strategy, starting with funnel audits, cohort analysis, and user behavioral segmentation. We use A/B and multivariate testing with Shopify Experiments and VWO to validate layout, copy, pricing, and promotion variations in real time. The results are integrated into custom Power BI dashboards, allowing the team to monitor KPIs such as CR, AOV, and LTV with automatic hourly updates. Thanks to caching optimizations, lazy image loading, and JavaScript reduction, we improve Core Web Vitals, bringing the LCP metric below 1.2 s and increasing the performance score by 10-15%.
