Who am i?
I’m Raira, a Brazilian developer who started working with technology as a teenager. Today, I’m a Senior Shopify Full-Stack Developer with 10+ years of experience building high-performance stores, headless architectures, and custom integrations. In those last years I’ve been turning a lot of e-commerce challenging projects into fast, accessible, and scalable solutions. My work revolves around Hydrogen/Next.js builds, Azure structures, Checkout Extensibility, advanced analytics pipelines, GA4/GTM/Klaviyo, and OneTrust compliance. Across global brands, I’ve led multi-region launches with a main focus on performance, UX, accessibility, and clean engineering practices.
