Full Stack Software Engineer · Shopify & Commerce Engineering
Rio de Janeiro, Brazil · Remote · English & Portuguese
I build web products and commerce systems from storefront to backend, with a growing specialization in Shopify.
TypeScript, Node.js, React, Next.js, PHP, WordPress, payments, integrations, infrastructure, and whatever else the project needs.
Shopify is my main specialization.
I’m focusing heavily on Shopify storefronts, Liquid themes, apps, Hydrogen/Oxygen, checkout extensibility, payments, integrations, performance, migrations, and the systems that connect commerce to real business operations.
I’m still a full stack engineer.
My work also covers SaaS products, marketplaces, APIs, payment systems, WordPress, WooCommerce, automation, backend services, frontend applications, and existing systems that need to be extended, stabilized, or rebuilt.
