Argentina

Message

At La Nuderia, I built and maintained a production ecommerce and online learning platform supporting PayPal and Mercado Pago transactions, authenticated courses, an admin dashboard, and protected Vimeo delivery. I also built an automotive platform for Autos al Rio, including its vehicle catalog, admin dashboard, and WhatsApp lead workflows.

Since 2024, I’ve architected and developed Austral yx, a multi-tenant SaaS platform with storefronts, tenant administration, an API gateway, and backend services. I designed tenant-isolated data architecture and implemented authentication, payments, and third-party integrations, alongside configurable storefronts and a visual editor.
