John Allen Hopper

I’m a Senior Software Engineer focused on building modern web applications and scalable digital platforms. My experience spans front-end development, full-stack systems, and high-performance web architecture. I specialize in developing robust user interfaces and translating product and design requirements into reliable, production-ready applications. My work often involves building reusable component systems, integrating APIs and third-party services, and creating maintainable codebases that support long-term product growth. I have extensive experience implementing responsive and accessible UI/UX across modern web platforms, ensuring that applications are intuitive for users and maintainable for engineering teams. Performance and reliability are central to my approach. I regularly work on application optimization, improving load performance, reducing client-side overhead, and ensuring systems remain stable and efficient under real-world usage. I have significant experience building headless commerce systems, including Shopify and Shopify Plus architectures, Hydrogen-based storefronts, and API-driven commerce integrations. I collaborate closely with product, design, and engineering teams to deliver scalable solutions that balance strong user experience, technical performance, and maintainability. My primary experience includes modern JavaScript frameworks, TypeScript, Node.js environments, Shopify Plus, headless and API-driven architectures, and modern development workflows including CI/CD and automated testing.
