I’m Romain Valla, a Los Angeles–based full-stack web engineer specializing in performant e-commerce and content platforms. Over the last 7+ years I’ve built and scaled sites across Shopify, WordPress, and modern headless stacks—pairing React/TypeScript with tools like Remix, Hydrogen, Sanity, and Oxygen to deliver fast, accessible, and maintainable systems. I founded Studio Antipodes to bring engineering discipline to design-driven brands: modular architectures, clean component libraries, and instrumentation baked in from day one (GTM, GA4, Meta Pixel, server-side tagging). My work has included custom Shopify themes, real-time inventory and variant logic, upsell flows, and analytics pipelines. Past projects report measurable gains in conversion and engagement thanks to performance tuning, Core Web Vitals improvements, and data-informed A/B tests. I collaborate closely with marketing, IT, and creative teams to align code quality with business goals—and I care about the details: accessibility, SEO, schema, and cross-browser reliability. Tooling & stack highlights: React, Node, TypeScript, Shopify (Liquid + headless), WordPress (custom themes/plugins), Sanity, GraphQL/REST, AWS/Firebase/Vercel, and CI/CD with Git.
